I think there's only one, and it's that they're autotrophs
They share their photosynthetic pigments and their cell wall composition.
they share peee
Green algae are considered the most closely related to green plants, as they share similar photosynthetic pigments and cell structure. The chlorophytes and charophytes groups of green algae are particularly close relatives to land plants.
The first plants evolved from a group of protists known as green algae. Green algae share many characteristics with plants, such as photosynthetic pigments and cell walls made of cellulose. This evolutionary relationship suggests that plants and green algae share a common ancestor.
Green algae, particularly charophytes, are considered to be the closest relatives and ancestors of land plants. They share many characteristics with land plants, such as similar chloroplast structure and reproductive features. This close evolutionary relationship suggests that land plants evolved from green algae.
Research on the ancestors of plants involved studying algae, as they are believed to be the ancestors of land plants. This is because algae and plants share common traits such as photosynthesis and cell structure. By analyzing the similarities and differences between algae and plants, scientists were able to trace the evolutionary history of plants.
All are embryophytes, and have evolved from algae
Actually, most algae is classified in the kingdom Protista. Cyanobacteria (also algae) is classified as a bacteria. Very few organisms that take the common name "algae" are still classified as plants. Response: So, no, algae is not a plant Response: yes
They share chlorophyll.
chloroplasts and cell walls
The ancestral group to all members of the Plant Kingdom is thought to be a group of freshwater green algae called Charophytes. These algae share many characteristics with land plants, such as similar cell structure and reproductive mechanisms. It is believed that plants evolved from these ancient green algae ancestors.
