How does the location of the female gametophyte of gymnosperms compare to that of angiosperms? A. In gymnosperms it is within a cone, and in angiosperms it is within a flower. B. It is found as cells within pollen grains in both gymnosperms and angiosperms. C. An ovule of both gymnosperms and angiosperms contains the female gametophyte. D. In gymnosperms it is found within a pollen grain, and in angiosperms it is found within a cone.
Answer
The correct comparison is:
C. An ovule of both gymnosperms and angiosperms contains the female gametophyte.
In both gymnosperms and angiosperms, the female gametophyte (or embryo sac) is located within the ovule. Here’s a brief explanation:
- Gymnosperms: In gymnosperms, the female gametophyte develops within the ovule, which is housed inside a cone (often called a strobilus).
- Angiosperms: In angiosperms, the female gametophyte is also located within the ovule, but the ovule is situated inside the ovary of a flower.
Thus, the common aspect is that the ovule in both groups contains the female gametophyte, although the overall structure and location within the plant are different.
