They all photosynthesize

Green algae or Chlorophytes
Cyanobacteria > Red Algae > Green Algae > Land Plants
Yeah buddie. And the other half is preformed by the lovely land plants that cause us to thrive. XD

Contain vascular tissue
No. The only living organisms that undergo phtosythesis are plants on land and phytoplankton in water.
Some green algae are unicellular
autotrophs
Nonvascular plants and seedless vascular plants are both land plants that evolved from green algae. Both types also rely on water to be able to reproduce.
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.
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 algea
Green algae absorbs oxygen from the surrounding water. Land plants had to evolve to absorb oxygen from the air.
Green and red algae are in the same eukaryotic supergroup as land plants.
