The reason biologists believe that green algae and land plants, both members of the supergroup archaeplastida, are related is because both of them possess chlorophyll a & b as well as cell walls made of starch.
a. True
b. False
The green algae and land plants both are photosynthetic in nature and prepare their own food. They have photosynthetic pigments chlorophyll a and b. These also have cell walls that contain starch in them. Due to all these similarities, green algae and land plants are kept together in the subgroup Archaeplastida.
