In seed plants, what is an important difference between gymnosperms and most angiosperms? A. Gymnosperms rely on animals to carry pollen from the female gametophyte to the male gametophyte, while angiosperms rely on wind. B. Gymnosperms require water for sperm to travel from the male gametophyte to the female gametophyte, while angiosperms do not rely on water for fertilization. C. In gymnosperms, male gametophytes and female gametophytes are produced in different structures, while in angiosperms they are usually produced in the same structure.

    Gymnosperms produce seed that is not protected by any fruit, but by a wooden casing like a cone.. Angiosperms produce flowers and fruit with one or more seed. The answer is C. It pays off to be a plant nut. :D

    The stems of such cacti store excess water, however they take the function of leaves by doing photosynthesis. The answer is A. Fun fact; Cacti have adapted their leaves as defense mechanisms, rather than food makers. (I.e. spines used to be leaves)
