The Three Key Reproductive Adaptations of Seed Plant Evolution Include

Question

The three key reproductive adaptations of seed plant evolution include
A)dominant sporophyte, cones, ovules.
B)dominant gametophyte, spores, seeds.
C)dominant sporophyte, seeds, pollen.
D)sporophylls, strobili, cones.
E)homospory, spores, cones.

Accepted Answer

The three key reproductive adaptations of seed plant evolution are the dominant sporophyte generation, which is larger and more complex than the gametophyte generation, the development of seeds, and the evolution of pollen as a means of transferring sperm to the female gametophyte. These adaptations are found in choice C, which includes dominant sporophyte, seeds, and pollen. Choice A includes cones and ovules, which are related to seed production but do not fully capture all three adaptations. Choices B and E refer to gametophyte dominance and spores, which were characteristics of early plant evolution but are not specific to seed plants. Choice D includes sporophylls and cones, which are closely related to the adaptations described in choice C but does not include seeds and pollen.
