chapter 6-Critical thinking

Only very few flowering plants have invaded the ocean,but those that have are very successful.What are some posible reasons for the small number of marine flowring plants? How do those that have taken the step manage to thrive in some environments?

- flowering plants live submerged by seawater,rearely exposed at low tide. Salt-marsh grasses and mangroves inhabit estuaries and shores protected from wave action. Their roots are usually covered by water at hight tide. They adapted to colonize coastal areas exposed to salt-laden winds and occasional sea spray,though they do not tolerate immersion in seawater. They can live on the sand dunes or living along the edges of salt marshes.
