What 2 adaptations were necessary for photosynthetic algae to make the transition from aquatic (water)?

Question

photosynthetic algae referring to either spirogyra, volvox, rhizopus and/or mushroom?

from water to land**** (photosynthetic algae referring to either spirogyra, volvox, rhizopus and/or mushroom?)

Answer 1

Spirogyra and Volvox are photosynthetic algae, but the other two are fungi.

To move to land:
1. They needed a waxy cuticle layer over any leaf-like parts to prevent water loss.
2. They needed vascular tissue to transport water within the plant and to help support the plant when it isn't surrounded by water.

Answer 2

Some also say lignins, which give more structure contributed.
