Most green algae live in freshwater habitats with highly variable conditions. The ongoing changes in their environment have made them highly adaptable. http://www.answers.com/topic/what-evidence-has-led-scientists-to-believe-land-plants-evolved-from-green-algae

There is no connective tissue is algae. Secondly, the reproduction system of plants is more developed while that of algae is primitive. Thirdly, algae can be single-celled while plants are multicellular organisms. Another area of difference between plants and…
