Question 4
In a flower, which structure acts as the female reproductive cell?
The right answer is the one marked above.
The ovule. The ovules are situated within the ovary, and it is the ovule that acts as the female reproductive cell in flowers.
The ovary is the container the ovules sit in, not the cell itself — that is the commonest slip here. The stigma is where pollen lands, and the pollen is the male reproductive cell.
