Akey difference between green algae and land based plants is that

Green Algae can either be unicellular ( single-celled) or multi-cellular while land bases plants are typically multi-cellular organisms ( made up of many cells)

Explanation:

A key difference between green algae and land based plants is that; while plants are typically multi-cellular organisms, Algae can either be unicellular     ( single-celled) or multi-cellular.

Thus the key difference between green algae and land based plants is their complexity. Algae are simple organisms while plants are complex, with several specialized structures.
