1.
Check the parts of the flowers which are accessory parts.
Correct Answer(s)
A. Sepals
D. Pendacle
E. Receptacle
F. Petals
Explanation
The correct answer includes the parts of a flower that are considered accessory parts. Sepals are the outermost part of the flower, protecting the developing bud. The pendacle refers to the stalk that connects the flower to the stem. The receptacle is the base of the flower where all the other parts are attached. Petals are the colorful, often fragrant part of the flower that attracts pollinators. Therefore, sepals, pendacle, receptacle, and petals are all accessory parts of a flower.
2.
Check the parts of the flowers which are essential parts.
Correct Answer(s)
B. Pistil
C. Stamen
Explanation
The pistil and stamen are essential parts of a flower. The pistil is the female reproductive organ, consisting of the stigma, style, and ovary. It is responsible for receiving pollen and producing seeds. The stamen is the male reproductive organ, consisting of the anther and filament. It produces and releases pollen, which fertilizes the pistil. These two parts are crucial for the sexual reproduction of flowering plants. The other listed parts, such as sepals, petals, pendacle, and receptacle, may have important roles in protecting and supporting the reproductive organs, but they are not directly involved in the reproductive process.
3.
Tiny leaf-like structure of the flower located in its base; it covers and protects the bud.
Correct Answer
A. Sepal
Explanation
The tiny leaf-like structure located at the base of a flower is called a sepal. The sepal covers and protects the bud of the flower. It is usually green in color and can be found just below the petals. Sepals play an important role in protecting the developing bud from external factors such as insects, wind, and harsh weather conditions.
4.
Also called pedicel; a flower stalk that supports the flower.
Correct Answer
D. Pendacle
5.
Colored and attractive part of the flower.
Correct Answer
B. Petal
Explanation
Petal is the correct answer because petals are the colored and attractive part of a flower. They are often brightly colored and serve to attract pollinators such as bees and butterflies. Petals are usually located inside the sepals, which are the protective outer covering of the flower bud. The pistil is the female reproductive part of the flower, while the pendacle is not a recognized botanical term.
6.
The structure located at the end of the flower stalk bearing the reproductive organs.
Correct Answer
C. Receptacle
Explanation
The structure located at the end of the flower stalk bearing the reproductive organs is called the receptacle. The receptacle is the base of the flower where all the floral parts are attached. It provides support for the flower and holds the reproductive organs, including the pistil and stamen. The pistil is the female reproductive organ, consisting of the stigma, style, and ovary. The stamen is the male reproductive organ, consisting of the anther and filament. However, neither the pistil nor the stamen specifically refers to the structure located at the end of the flower stalk, making receptacle the correct answer.
7.
A tube leading to the ovary.
Correct Answer
C. Style
Explanation
The style is a long, slender tube that connects the stigma to the ovary in a flower. It serves as a pathway for the pollen to travel from the stigma to the ovary, where fertilization takes place. The style is an important part of the pistil, which is the female reproductive organ of a flower. The stamen, on the other hand, is the male reproductive organ, consisting of the anther and filament. Therefore, the style is the correct answer as it is the tube leading to the ovary.
8.
The female part of the flower.
Correct Answer
A. Pistil
Explanation
The pistil is the female reproductive part of a flower. It is composed of three main parts: the stigma, style, and ovary. The stigma is the sticky structure at the top of the pistil that receives pollen. The style is a long tube-like structure that connects the stigma to the ovary. The ovary is the enlarged base of the pistil that contains the ovules, which will develop into seeds if fertilized. Therefore, the pistil is the correct answer as it encompasses all three parts mentioned in the options.
9.
The male part of the flower.
Correct Answer
B. Stamen
Explanation
The stamen is the male part of the flower, consisting of the filament and anther. The filament is a long, slender stalk that holds up the anther, which is the part that produces pollen. The stamen is responsible for the production and release of pollen, which is necessary for fertilization to occur. In contrast, the pistil is the female part of the flower, consisting of the stigma, style, and ovary. The stigma is the receptive surface that collects pollen, while the style is the slender tube that connects the stigma to the ovary.
10.
A swollen base connected to the receptacle of the flower stalk; holds the ovule that contains the egg cell.
Correct Answer
B. Ovary
Explanation
The correct answer is ovary. The ovary is a swollen base connected to the receptacle of the flower stalk. It holds the ovules, which contain the egg cells. The ovary is an essential part of the female reproductive system in plants, as it protects and nourishes the developing seeds.
11.
Divisions of the ovary of the flower.
Correct Answer
D. Carpel
Explanation
The carpel is the female reproductive organ of a flower, consisting of the ovary, style, and stigma. It is responsible for producing and protecting the ovules, which contain the female gametes. The ovary is the enlarged basal portion of the carpel that contains the ovules. Therefore, the carpel is directly related to the divisions of the ovary and the production of ovules.
12.
Structure in the ovary which can be a fertilized seed.
Correct Answer
C. Ovules
Explanation
The structure in the ovary that can be a fertilized seed is called ovules. Ovules are the female reproductive structures found in the ovary of a flower. They contain the egg cell and are responsible for the production of seeds after fertilization. Ovules develop into seeds when they are fertilized by pollen from the male reproductive structures of the flower. Therefore, ovules are the correct answer in this context.
13.
Cavity inside a particle.
Correct Answer
A. Locule
Explanation
A locule refers to the cavity or chamber inside a plant structure, such as an ovary or fruit, where seeds or ovules are produced and stored. In this context, the correct answer is "locule" because it directly relates to the given statement about a cavity inside a particle. The other options, such as ovary, ovules, and carpel, are related to reproductive structures in plants but do not specifically refer to a cavity.
14.
Helps in reproduction but are not directly involved with it.
Correct Answer
A. Accessory parts
Explanation
Accessory parts refer to the components or structures that support or assist in the process of reproduction but are not directly involved in it. These parts may include organs or structures that facilitate the transfer of gametes, provide protection or nourishment to the developing embryo or fetus, or play a role in attracting potential mates. While essential parts are directly involved in the reproductive process, accessory parts play a supportive or secondary role in ensuring successful reproduction.
15.
Parts of the flower that are directly involved in reproduction.
Correct Answer
B. Essential parts
Explanation
The essential parts of a flower are directly involved in reproduction. These parts include the pistil, which contains the ovary, style, and stigma, and the stamens, which produce pollen. The pistil is responsible for producing and protecting the female reproductive cells, while the stamens produce and release the male reproductive cells. Without these essential parts, the flower would not be able to reproduce and produce seeds.
16.
Has both stamen and pistil; bisexual.
Correct Answer
C. Perfect flower
Explanation
A perfect flower is one that has both stamen and pistil, making it bisexual. This means that it contains both male and female reproductive organs, allowing it to self-pollinate and produce seeds. This term is used to describe flowers that have all the necessary parts for sexual reproduction in a single flower.
17.
Lacks one of the reproductive parts.
Correct Answer
D. Imperfect flower
Explanation
An imperfect flower is one that lacks one of the reproductive parts, either the stamen or the pistil. This means that it is unable to produce both male and female gametes, and therefore cannot undergo complete sexual reproduction. In contrast, a complete flower has both stamen and pistil, allowing for the production of both male and female gametes. A perfect flower, on the other hand, refers to a flower that has both stamen and pistil and is capable of self-pollination. Therefore, an imperfect flower is the correct answer as it accurately describes a flower that is missing one of the reproductive parts.
18.
Has the pistil of the flower.
Correct Answer
B. Pistillate
Explanation
The correct answer is "pistillate" because the pistil is the female reproductive part of a flower, which contains the ovary, style, and stigma. A pistillate flower only has pistils and does not have stamens, which are the male reproductive parts. Therefore, a flower that has a pistil is referred to as pistillate.
19.
Has the stamen of the flower.
Correct Answer
A. Staminate
Explanation
The correct answer is "staminate" because the stamen is the male reproductive organ of a flower, which produces pollen. A staminate flower only has stamens and does not have a pistil, which is the female reproductive organ. Therefore, a flower with only stamens would be classified as staminate.
20.
Check the parts of the pistil.
Correct Answer(s)
C. Stigma
D. Style
E. Ovary
Explanation
The pistil is the female reproductive part of a flower. It consists of three main parts: the stigma, style, and ovary. The stigma is the sticky surface at the top of the pistil, where pollen grains land and germinate. The style is the long tube-like structure that connects the stigma to the ovary. It provides a pathway for the pollen tubes to grow and reach the ovary. The ovary is located at the base of the pistil and contains the ovules, which are the structures that develop into seeds after fertilization. Therefore, the correct answer includes the stigma, style, and ovary as the parts of the pistil.
21.
Corolla is a group of petals.
Correct Answer
A. True
Explanation
The statement is true because a corolla refers to the collection of petals in a flower. The corolla is the innermost part of the flower and is composed of petals, which are often colorful and fragrant. Therefore, it can be concluded that a corolla is indeed a group of petals.
22.
Calyx is a collective term for sepals.
Correct Answer
A. True
Explanation
The statement is true because calyx is indeed a collective term for sepals. The calyx is the outermost whorl of a flower, and it consists of sepals, which are leaf-like structures that protect the flower bud before it blooms. So, when we refer to the calyx, we are referring to the collection of sepals.
23.
Perianth is the group of petals and sepals.
Correct Answer
A. True
Explanation
The statement is true because the perianth is indeed the collective term used to describe the group of petals and sepals in a flower. The perianth is the outermost part of the flower and is made up of the petals, which are usually colorful and attract pollinators, and the sepals, which are typically green and protect the developing bud. Together, the petals and sepals form the perianth, which plays an important role in attracting pollinators and protecting the reproductive organs of the flower.
24.
Grouped into 2 large groups.
Correct Answer
plant
plants
Explanation
The correct answer is "plant, plants" because the given statement mentions that the items are "grouped into 2 large groups." The words "plant" and "plants" are both related to the topic of vegetation, and it is common to group them together as they represent the singular and plural forms of the same word. Therefore, it makes sense for these two words to be grouped together in the answer.
