Question

what are seagrasses​

Answer 1

Answer:

Seagrasses are flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families, all in the order Alismatales. Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago.

Explanation:

Seagrasses are marine flowering plants, found on all continents except Antarctica. They have roots, stems and leaves and produce flowers and fruits. They are closely related to land plants, and probably evolved from land-living angiosperms (flowering plants) millions of years ago. The closest relatives to seagrass, on land, are the monocots – grasses, lilies and palms.
