Charophyceae is considered (the green algae) ancestor for land plants. Here's why(similarities): 1)Chloroplast structure:- Chloroplast DNA is closely matched 2)Biochemistry:- Cell walls-Rosette cellulose 3)mitosis:- Phragmoplast is present during cell plate formation

It is more that they are considered to share a common ancestor because they have the same photosynthetic pigments.
because green algae and plant cells have the same kind of chlorophyll, they have similar wall cells, both make their own food during photosynthesis, both store energy in the form of starch, and both have two stage life cycles.

The green algae that plants most likely descended from are unicellular and colonial flagellates as well as macroscopic seaweeds.

Green algae is the oldest ancestor of what organism?

Green algae is the oldest ancestor of all land dwelling (non-marine) plants.


From what is it believed land plants evolved?

Land plants are believed to have evolved from algae that came from oceans, to freshwater, to wet-dry coatlines, and developed into ferns/shrubs.


Why do biologists classify red and green algae with land plants?

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.

Green algae or Chlorophytes


Is land an autotroph?

No, plants (on land) and algae (in water) are autotrophs.


What is the evidence that land plants evolved from green algae?

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


What are the oldest ancestors of plants?

Probably the green algae, which descended from cyanobacteria. Seaweeds come in three colours, green, brown and red, and each has different photosynthetic mechanisms - not only chlorophyll. The intertidal zone may have played an important part in the colonization of the land from aquatic plants.


In what ways did land plants need to be different from green algae?

Green algae absorbs oxygen from the surrounding water. Land plants had to evolve to absorb oxygen from the air.


What kind of plant was most likely the first land plant?

Since all known land plants have a vascular system, it is likely that the first land plant also had a vascular system. Researchers believe that there were two types of plants that may have been the first land plants. These are called rhynia and zosterophyllum.
