Chapter 18, Problem 5FIB
Summary Introduction
Introduction:
Reproduction out of water presented challenges to the plants such as plant produce eggs and sperms and these gametes must meet to produce the next generation. The first land plant has swimming sperms. Meanwhile, some plants residing in drier regions had evolved a means of reproduction that no longer depended on water. The eggs of such plants retained on the parent plant and sperms were “encased in drought-resistant pollen grains” that were carried by wind from plant to plant for pollination.
