Identify and name the two parts in a flower which are most important units of sexual reproduction?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3): 3-Anther, 7-ovary
Anther: The anther is part of the stamen (male reproductive organ) and is responsible for producing and releasing pollen grains, which contain the male gametes (sperm cells).
Ovary: The ovary is part of the pistil (female reproductive organ) and contains the ovules. The ovules develop into seeds after fertilization, and the ovary itself matures into a fruit.
These two structures are directly involved in the process of sexual reproduction in flowering plants. The anther produces the pollen that fertilizes the ovules within the ovary.
Other Parts:
- Style and Stigma: Part of the female reproductive system but not directly producing gametes.
- Filament: Part of the stamen that supports the anther.
- Thalamus: The base of the flower, supporting the floral organs.
- Sepals: Typically protective structures that enclose the flower bud.
Thus, the correct answer is: 3-Anther, 7-Ovary
