Red and green algae are photosynthetic and are thus autotrophs. Otherwise, they are aquatic and (in the case of green algae) can be unicellular. But these are similarities that are not sufficient to define algae as true plants. All plants in the Kingdom Plantae are multicellular and terrestrial (ancestrally terrestrial in the case of waterlilies). Green algae are important in the study of plants as they show the base of the plant kingdom, hinting at what a common ancestor to the whole kingdom may have looked like. In particular, the charophytes are probably close to the common ancestor of all land plants. Thus, in the study of land plants, green algae can be considered the most recently diverged outgroup. And, earlier still, red algae diverged.
Some green algae are unicellular
Plants enclose and protect the embryo within the female plant while green algae do not.
Many scientists believe that ancient green algae evolved into land plants. The chloroplasts present in green algae are the same as those of land plants. In addition, green algae have cell walls of similar composition to land plants; both store food, such as starch, in the same manner. Most green algae live in freshwater habitats with highly variable conditions. The ongoing changes in their environment have made them highly adaptable.what-evidence-has-led-scientists-to-believe-land-plants-evolved-from-green-algae
Green Algae is unicellular because it only grows on non-vascular plants which are plants with no tubes to carry nu trains and oxygen.
Plants and green algae have the same types of chlorophyll and carotenoids in their cells so scientists think plants and green algae have a common ancestor.
Because their basic cellular composition remains similar to the modern plants.

The ancestors of land plants, green algae, lack the structural support to stand erect in air.

Cyanobacteria > Red Algae > Green Algae > Land Plants
Yes they are non-green plantsAdditional answerHey, no. There are plenty of green algae!

Green Algae is not even classified as plants in the first place yah big dummy!
because its full of plants and plants are full choraphyll and chloraplats with are green wich causes the plant to become green.
