Why are Green Algae considered as the Ancestors of Land Plants? The green algae are considered as the ancestors of land plants due to the presence of morphological, cytological and biochemical similarities, and phylogenetic evidence.
Some of the points in support of this view are briefly given below:
- Like land plants, the green algae possess photosynthetic pigments such as chlorophyll a, chlorophyll b, and carotenoids.
- The cell wall of both green algae and land plants is made of cellulose and pectose.
- In both green algae and land plants, the reserve food material is starch.
- The motile forms of both the groups flagella with a similar structure.
- The Definite tendency is observing among the members of Chlorophyceae to migrate towards land and lead life like land plants.
