What are annuals?
Correct Answer
C. As a one year life cycle
Explanation
Annuals are plants that complete their life cycle in just one year. This means that they germinate, grow, flower, produce seeds, and die within a single year. Unlike perennial plants that live for multiple years, annuals complete their entire life cycle in a shorter period. This adaptation allows them to quickly reproduce and spread their seeds, taking advantage of favorable growing conditions. Annual plants are commonly found in gardens and cultivated for their vibrant flowers or edible fruits and vegetables.
2.
What are perennials?
Correct Answer
A. Has several years to complete a life cycle
Explanation
Perennials are plants that have several years to complete their life cycle. Unlike annuals, which complete their life cycle in one year, perennials live for multiple years. They can survive through different seasons and continue to grow and reproduce year after year. This characteristic allows perennials to establish deep root systems and develop stronger structures, making them more resilient and long-lasting compared to other types of plants.
3.
What is a peduncle?
Correct Answer
C. Flower Stalk
Explanation
A peduncle refers to the flower stalk, which is the structure that supports the flower and connects it to the main stem or branch of the plant. It provides support and allows the flower to be elevated for better visibility, pollination, and seed dispersal. The peduncle also transports water, nutrients, and sugars to and from the flower, aiding in its growth and development.
4.
What is a receptacle?
Correct Answer
B. Swelling on the tip of peduncle that the other parts of the flower attach to
Explanation
A receptacle in a flower refers to the swelling on the tip of the peduncle where the other parts of the flower attach. It acts as a base for the attachment of sepals, petals, stamens, and pistils. The receptacle provides support and allows these floral organs to be arranged in a specific pattern. It is an essential part of the flower's structure and plays a crucial role in the overall development and function of the flower.
5.
What are the characteristics of sepals?
Correct Answer(s)
A. Small, usually green leaf-like structures
B. Referred to as the calyx
E. The outermost whorl and there are 3-5 sepals
Explanation
Sepals are small, usually green leaf-like structures that are referred to as the calyx. They are the outermost whorl of a flower and there are typically 3-5 sepals.
6.
What are the characteristics of petals?
Correct Answer(s)
B. Known as the corolla
D. Missing in wind pollinated plants
E. The next whorl of flower parts
Explanation
Petals are known as the corolla and are the next whorl of flower parts. They are usually attached to the receptacle and play a role in attracting pollinators. However, they are missing in wind-pollinated plants, as these plants do not rely on pollinators for reproduction.
7.
What are the characteristics of stamens?
Correct Answer
A. Attached to the receptacle
Explanation
The characteristics of stamens are that they are attached to the receptacle, meaning they are connected to the base of the flower. They are usually small in size and often green in color. Stamens are also part of the outermost whorl of floral organs, which means they are located towards the outer edge of the flower structure.
8.
What is perianth?
Correct Answer
B. Refers to the calyx and the corolla together
Explanation
Perianth refers to the calyx and the corolla together. The calyx is the outermost whorl of a flower that protects the developing bud, while the corolla is the second whorl that consists of the petals and is responsible for attracting pollinators. Therefore, perianth encompasses both the calyx and the corolla, representing the outer non-reproductive parts of the flower.
9.
What is a filament?
Correct Answer
A. Slender structure
Explanation
A filament is a slender structure that is part of a flower. It is specifically the stalk-like structure that holds up the anther, which is the part of the flower that produces pollen. The filament is usually long and thin, allowing the anther to be positioned in a way that maximizes the exposure of the pollen to pollinators.
10.
What is anther?
Correct Answer
B. Produces pollen
Explanation
Anther refers to the part of a flower that produces pollen. It is a crucial reproductive structure in plants, responsible for the production and release of pollen grains. The anther is typically located at the top of the stamen, which is the male reproductive organ of a flower. Pollen produced by the anther plays a vital role in the fertilization of plants, as it is transferred to the stigma of the female flower parts, leading to the formation of seeds and fruits.
11.
What are the characteristics of a pistil?
Correct Answer(s)
A. Often vase-shaped
B. Has a stigma
C. Has a style
D. Has an ovary
Explanation
A pistil is the female reproductive part of a flower. It is often vase-shaped, with a stigma, style, and ovary. The stigma is the sticky surface where pollen is received, the style is the tube connecting the stigma to the ovary, and the ovary contains the ovules, which develop into seeds after fertilization. These characteristics are essential for the pistil's role in reproduction, as they allow for the reception, transfer, and development of pollen.
12.
Which of the following is the correct definition for stigma?
Correct Answer
C. At the top of the pistil
Explanation
The correct definition for stigma is "at the top of the pistil." The stigma is a part of the female reproductive structure of a flower called the pistil. It is located at the top of the pistil and is responsible for receiving pollen during pollination.
13.
Which of the following is the correct definition for style?
Correct Answer
A. Connects the stigma & ovary
Explanation
The correct definition for style is that it connects the stigma and ovary. The style is a part of the pistil, which is the female reproductive organ of a flower. It is located at the top of the pistil and has a swollen base. The style plays a crucial role in the process of pollination, as it allows the pollen to travel from the stigma to the ovary, where fertilization takes place.
14.
Which of the following is the correct definition for ovary?
Correct Answer
A. Swollen base
Explanation
The correct definition for ovary is a swollen base. This is because the ovary is the part of a flower's reproductive system that contains the ovules, which eventually develop into seeds. It is located at the base of the pistil, the female reproductive organ of a flower. The ovary is responsible for producing and releasing eggs for fertilization.
15.
Ovary wall develops into a fruit which surrounds the seeds
Correct Answer
A. True
Explanation
The statement is true because in many plants, the ovary wall develops into a fruit that surrounds the seeds. This process is known as fruit development and it occurs after fertilization. The ovary wall undergoes changes, such as thickening and enlargement, to form the fruit. The fruit provides protection and aids in seed dispersal, allowing for the successful reproduction of the plant.
16.
What are ovules?
Correct Answer
B. Egg-shaped and attached to ovary wall
Explanation
Ovules are egg-shaped structures that are attached to the ovary wall. They are part of the female reproductive system of plants and contain the female gametes, or eggs. Ovules develop into seeds after fertilization occurs.
17.
An ovary position is a mature ovary and accessory parts that usually contains seeds
Correct Answer
B. False
Explanation
An ovary position is the position of the ovary in relation to where the calyx and the corolla attach to the receptacle
18.
The ovary is above the calyx and corolla is known as:The receptacle grows up and around the ovary and the ovary appears to be below the calyx and corolla is known as:
Correct Answer
B. Superior; Inferior
Explanation
The correct answer is "Superior; Inferior." In this case, the receptacle grows up and around the ovary, causing the ovary to appear below the calyx and corolla. This arrangement is referred to as "inferior." On the other hand, the calyx and corolla are positioned above the ovary, making them "superior."
19.
Inflorescence is a single peduncle which leads to the flowers and a pedicel, then leads to each flower
Correct Answer
A. True
Explanation
An inflorescence refers to a cluster of flowers that are arranged on a single peduncle. The peduncle acts as the main stalk or support for the entire inflorescence. Each individual flower within the inflorescence is attached to the peduncle by a smaller stalk called the pedicel. Therefore, the statement that inflorescence is a single peduncle which leads to the flowers and a pedicel, then leads to each flower is true.
20.
A nut is a mature ovary and accessory parts that usually contains seeds
Correct Answer
B. False
Explanation
A FRUIT is a mature ovary and accessory parts that usually contains seeds
21.
Which regions together are called the pericarp?
Correct Answer(s)
A. Mesocarp
B. Endocarp
C. Exocarp
Explanation
The pericarp is the protective layer that surrounds the seed in a fruit. It is made up of three regions: the mesocarp, endocarp, and exocarp. The mesocarp is the middle layer of the pericarp, which is often fleshy and contains the majority of the fruit's tissue. The endocarp is the innermost layer of the pericarp, which directly surrounds the seed. The exocarp is the outermost layer of the pericarp, which is typically the skin or peel of the fruit. Together, these three regions make up the pericarp.
22.
What is the exocarp?
Correct Answer
B. Outer skin
Explanation
The exocarp refers to the outer skin of a fruit. It is the outermost layer of the fruit that protects the inner parts, such as the seed(s) and the mesocarp. The exocarp can vary in texture and thickness depending on the fruit type, but its main function is to provide a barrier against external factors and to help retain moisture within the fruit.
23.
What is the mesocarp?
Correct Answer
A. Everything in between
Explanation
The mesocarp refers to everything in between the outer skin and the inner boundary around the seed(s). It is the middle layer of a fruit that is responsible for protecting the seeds and providing them with nutrients. The mesocarp is usually fleshy and can vary in texture and taste depending on the type of fruit. It plays a crucial role in the development and dispersal of seeds.
24.
What is the endocarp?
Correct Answer
A. Inner boundary around the seed(s)
Explanation
The endocarp refers to the inner boundary that surrounds the seed(s) of a fruit. It is the layer that provides protection and support to the seed(s) within the fruit. This boundary separates the seed(s) from the mesocarp and the exocarp, which are the other layers of the fruit.
25.
Which of the following are true about simple fleshy fruits?
Correct Answer(s)
A. Develop from a single flower with a single pistil
C. Mesocarp is fleshy at maturity
Explanation
Simple fleshy fruits develop from a single flower with a single pistil. This means that the fruit is formed from the ovary of a single flower, which contains a single pistil. The ovaries of these fruits do not fuse together, so they do not form a single fruit. Additionally, the mesocarp of simple fleshy fruits is fleshy at maturity, which means that the middle layer of the fruit becomes soft and juicy as it ripens.
26.
Which of the following are characteristics of drupes?
Correct Answer
A. Single seed within a hard, stony endocarp (pit)

Which of the following are characteristics of dry fruits?
Correct Answer(s)
A. Mesocarp is dry at maturity
C. Split at maturity
Explanation
Dry fruits are characterized by having a dry mesocarp at maturity and splitting open when they are fully mature. These characteristics distinguish them from fleshy fruits, which have a moist or fleshy mesocarp and do not split open when mature. The cup formed from bracts attached to the bottom is not a characteristic of dry fruits, but rather a characteristic of some other types of fruits, such as acorns.

45.
What do seeds consist of?
Correct Answer(s)
A. Cotyledons
B. Embryo
C. Seed Coat
Explanation
Seeds consist of cotyledons, which are the embryonic leaves of the plant. They also contain an embryo, which is the young, developing plant. Additionally, seeds have a seed coat, which is the protective outer covering that helps to prevent damage and drying out of the embryo.
46.
What is epicotyl?
Correct Answer
A. The stem above the cotyledons
Explanation
The epicotyl refers to the stem that is located above the cotyledons in a plant. This part of the stem is responsible for the development of the upper portion of the plant, including the leaves and flowers. It is an important part of the plant's growth and plays a crucial role in determining the overall structure and form of the plant.
47.
What is hypocotyl?
Correct Answer
B. The stem between the cotyledons and the radicle
Explanation
The hypocotyl refers to the stem of a young plant embryo that is located between the cotyledons (seed leaves) and the radicle (embryonic root). It is responsible for connecting the cotyledons to the developing root system. As the plant grows, the hypocotyl elongates and pushes the cotyledons above the soil surface, allowing them to receive sunlight for photosynthesis. Eventually, the hypocotyl develops into the lower part of the stem, while the radicle develops into the roots.
48.
What is the radicle?
Correct Answer
A. Develops into the roots
Explanation
The radicle is the part of a plant embryo that develops into the roots. It is the first organ to emerge from the seed during germination and plays a crucial role in anchoring the plant and absorbing water and nutrients from the soil. The radicle is located below the cotyledons, which are the embryonic leaves, and above the stem. As the plant grows, the radicle elongates and gives rise to the primary root, which then branches out into secondary roots, forming the root system of the plant.
49.
How many cotyledons do monocots have?
Correct Answer
A. 1
Explanation
Monocots have only one cotyledon. Cotyledons are embryonic leaves that provide nutrients to the developing plant. In monocots, such as grasses and lilies, the seed typically contains a single cotyledon, while in dicots, like beans and roses, there are usually two cotyledons. The number of cotyledons is one of the key characteristics used to differentiate between these two major groups of flowering plants.
50.
How many cotyledons do dicots have?
Correct Answer
B. 2
Explanation
Dicots have two cotyledons. Cotyledons are the embryonic leaves of a plant that emerge from the seed upon germination. In dicots, the seeds typically have two cotyledons, which serve to provide nutrients to the developing plant until it can produce its own food through photosynthesis. This is in contrast to monocots, which have only one cotyledon. The presence of two cotyledons is a distinguishing characteristic of dicots and helps classify them as a separate group of flowering plants.
