In what stage are egg and sperm cells produced in a plant?
- A.
Gametophyte
- B.
Sporophyte
- C.
Lickophyte
Correct Answer
A. GametopHyteExplanation
The correct answer is Gametophyte because in plants, the gametophyte stage is where egg and sperm cells are produced. The gametophyte is the haploid stage of the plant's life cycle, and it is responsible for producing the gametes through the process of mitosis. This stage is characterized by the production of male and female gametophytes, which eventually give rise to the sperm and egg cells respectively. The gametes then fuse during fertilization to form a diploid zygote, which develops into the sporophyte stage of the plant's life cycle.Rate this question:

What are the two stages of a plant's life?
- A.
Sporophyte and Gametophyte
- B.
Lickophyte and Sporophyte
- C.
Baby and Adult
Correct Answer
A. SporopHyte and GametopHyteExplanation
The two stages of a plant's life are sporophyte and gametophyte. The sporophyte stage is the diploid phase where the plant produces spores through meiosis. These spores then develop into the gametophyte stage, which is the haploid phase. In the gametophyte stage, the plant produces gametes through mitosis. Fertilization of the gametes leads to the formation of a new sporophyte, completing the plant's life cycle.Rate this question:

What determines a flower's time of flowering?
- A.
Heat
- B.
Light/ Darkness
- C.
Water
Correct Answer
B. Light/ DarknessExplanation
Light and darkness play a crucial role in determining a flower's time of flowering. This is because plants have a natural response to the duration of daylight and darkness, known as photoperiodism. Different plants have different requirements for the length of light and darkness they need to initiate flowering. Some plants require shorter days or longer nights, while others require longer days or shorter nights. This response is controlled by specific proteins in the plant's cells that detect the duration of light and darkness. Therefore, light and darkness are key factors in regulating a flower's time of flowering.Rate this question:

What happens when the zygote is formed?
- A.
Pollen falls on the anther.
- B.
Pollen falls on the stigma.
- C.
Pollen falls on the style.
Correct Answer
B. Pollen falls on the stigma.Explanation
When the zygote is formed, it means that fertilization has taken place between the male and female gametes. In plants, this occurs when pollen, which contains the male gametes, falls on the stigma, which is part of the female reproductive structure. The pollen then germinates and grows a pollen tube through the style, allowing the male gametes to reach the ovary and fertilize the egg, resulting in the formation of a zygote. Therefore, the correct answer is "Pollen falls on the stigma."Rate this question:
