An immature plant.
-
Spores
-
Embryo
-
Seed
Correct Answer
A. EmbryoExplanation
The correct answer is embryo. An embryo refers to the early stage of development in a plant or animal. In the context of plants, an embryo is the young, undeveloped plant that is contained within a seed. It is the part of the seed that has the potential to grow into a mature plant. Spores, on the other hand, are reproductive structures that are produced by certain plants and fungi. While seeds also play a role in plant reproduction, they specifically refer to the mature ovule of a plant that contains an embryo.Rate this question:

Plants that do not produce flowers nor fruits? Example: Conifer
-
Gymnosperms
-
Angiosperms
-
Ferns
Correct Answer
A. GymnospermsExplanation
Gymnosperms are plants that do not produce flowers nor fruits. They are a group of seed-bearing plants that produce naked seeds, meaning their seeds are not enclosed within a fruit. Instead, the seeds are usually found on the surface of cones or in other structures. This is in contrast to angiosperms, which are flowering plants that produce seeds enclosed within a fruit. Ferns, on the other hand, are a type of non-flowering vascular plant that reproduces through spores, not seeds.Rate this question:

The female part or a plant that secures the ovary to the stigma is what part of a flower?
-
Stamen
-
Pistil
-
Tropism
Correct Answer
A. PistilExplanation
The pistil is the correct answer because it is the female reproductive organ of a flower. It consists of three main parts: the stigma, style, and ovary. The stigma is the sticky surface where pollen is deposited, and it is connected to the ovary by the style. The ovary contains the ovules which eventually develop into seeds after fertilization. Therefore, the pistil plays a crucial role in the reproduction of flowering plants by securing the ovary to the stigma.Rate this question:
-
- 9.
The transfer of pollen to the stigma is what?
-
Pollination
-
Rhizoids
-
Rhizomes
Correct Answer
A. PollinationExplanation
Pollination refers to the transfer of pollen grains from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower. This process is crucial for the fertilization and reproduction of flowering plants. Pollen can be transferred through various agents such as wind, water, insects, birds, or other animals. Once the pollen reaches the stigma, it can germinate and grow a pollen tube, allowing the sperm cells to travel to the ovary and fertilize the ovules. Therefore, pollination plays a vital role in the sexual reproduction and survival of flowering plants.Rate this question:

Hair like fibers that hold mosses to the ground.
-
Rhizoids
-
Seed Coat
-
Embryo
Correct Answer
A. RhizoidsExplanation
Rhizoids are hair-like fibers that hold mosses to the ground. They act as anchors, allowing the moss to attach itself to various surfaces, such as soil, rocks, or tree bark. Rhizoids also aid in the absorption of water and nutrients from the environment. They are not true roots, as they do not perform the same functions as roots in vascular plants. Instead, rhizoids provide stability and support for the moss, allowing it to grow and thrive in its habitat.Rate this question:
-
- 11.
An underground stem of a fern?
-
Rhizomes
-
Tropism
-
Seed
Correct Answer
A. RhizomesExplanation
Rhizomes are underground stems of ferns that grow horizontally. They are responsible for the vegetative reproduction of the ferns, as they produce new shoots and roots. Rhizomes have nodes and internodes, and they store nutrients for the plant. They also help in anchoring the plant and absorbing water and nutrients from the soil. Therefore, rhizomes are the correct answer for the underground stem of a fern.Rate this question:
-
- 12.
Pollination within the same flower
-
Stamen
-
Embryo
-
Self Pollination
Correct Answer
A. Self PollinationExplanation
Self-pollination refers to the process where pollen from the stamen of a flower is transferred to the stigma of the same flower, leading to fertilization and the development of an embryo. This can occur due to various mechanisms such as wind, gravity, or the flower's own structure. Self-pollination is advantageous for plants as it ensures reproductive success even in the absence of external pollinators. It allows for the transfer of genetic material within the same plant, leading to the production of offspring with similar traits to the parent plant.Rate this question:

A response to a stimuli in plants. Can either be positive or negative
-
Frond
-
Tropism
-
Non vascular
Correct Answer
A. TropismExplanation
Tropism refers to the response of a plant to an external stimulus, which can be either positive or negative. It is a growth movement that occurs in response to specific environmental factors such as light, gravity, or touch. This response helps the plant to adapt and survive in its surroundings. Tropisms can be categorized into different types based on the stimulus, such as phototropism (response to light), gravitropism (response to gravity), and thigmotropism (response to touch). Therefore, the term "tropism" accurately describes the given explanation of a plant's response to stimuli.Rate this question:
