2.) Only very few flowering plants have invaded the oceans, but those that have are very successful. What are some possible reasons for the small number of marine flowering plants? How do those that have taken the step manage to thrive in some environments?
-An example is the Seagrass flowers, whose closest relatives seem to be members of the lily family, which shows that seagrasses evolved from land plants. But they have very well adapted to life in the marine environment. Instead of attracting insect for pollination, the pollen is carried by the water currents. Tiny seeds result from successful fertilization. These seeds are dispersed by water currents and perhaps in the feces of the fish and other animals that browse on the plants.
