Liverworts and mosses were some of the earliest land-based plants. Which statement correctly explains why these species are stil
l restricted to growing in moist environments? A. They can't absorb water through their roots and must do it through their leaves. B. Their gametes must swim in order to interact and for fertilization to occur. C. They don't have cell walls to retain moisture in their cells and dry out otherwise. D. Their seeds must absorb water in order to germinate.
Answer: B. Their gametes must swim in order to interact and for fertilization to occur.
Explanation:
Liverworts and mosses are the primitive plants used to have evolved from the aquatic life to terrestrial life. These plants are bryophytes and they do not exhibit true roots, stems and leaves. The reproduction in these organism is facilitated by water as the gametes swims in the water. The fusion or fertilization of the gametes takes place in water.
Deposition. The opposite of sublimation is deposition. This is the process in which a gas changes directly to a solid without going through the liquid state.
