LAND PLANTS or The embryophytes are the most familiar group of plants. They include ferns , mosses, trees , plants and various other green land plants. All are complex multicellular eukaryotes with specialized reproductive organs. With very few exceptions, embryophytes obtain their energy through photosynthesis (that is, by absorbing light); and they synthesize their food from carbon dioxide.
ALGAE Any of various chiefly aquatic, eukaryotic, photosynthetic organisms, ranging in size from single-celledforms to the giant kelp. There are many types of algae, but only red and green algae are considered plants.
One key structural difference between algae and land plants is that algae lack true roots, stems, and leaves, while land plants have well-defined vascular tissues that support them. Algae also lack specialized structures for reproduction, such as flowers or cones, which are present in many land plants. Additionally, algae typically have a simpler body structure compared to the more complex structures seen in land plants.
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.
Some green algae are unicellular
There is strong molecular and morphological evidence supporting the theory that land plants evolved from green algae. Both groups share similarities in their cell walls, chloroplast structure, and photosynthetic pigments. Additionally, genetic studies have shown a close evolutionary relationship between land plants and certain groups of green algae.
Protists in the supergroup Archaeplastida are in the same eukaryotic supergroup as land plants. This supergroup includes red algae, green algae, and land plants, which all share a common ancestor that underwent primary endosymbiosis with a cyanobacterium.
Because algae are aquatic plants while ferns are not.

Green algae or Chlorophytes
There is strong molecular and morphological evidence supporting the theory that land plants evolved from green algae. Both groups share similarities in their cell walls, chloroplast structure, and photosynthetic pigments. Additionally, genetic studies have shown a close evolutionary relationship between land plants and certain groups of green algae.
Green algae are members of the Kingdom Plantae and are thought to be the direct ancestor of land plants. This evolutionary relationship is supported by similarities in cell structure and photosynthetic pigments between green algae and land plants.
No, plants (on land) and algae (in water) are autotrophs.
Protists in the supergroup Archaeplastida are in the same eukaryotic supergroup as land plants. This supergroup includes red algae, green algae, and land plants, which all share a common ancestor that underwent primary endosymbiosis with a cyanobacterium.
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.
Green algae are a diverse group of photosynthetic organisms that can be unicellular, multicellular, or colonial, while charophytes specifically refer to a group of freshwater green algae that are closely related to land plants. Charophytes have adaptations that are thought to be ancestral to land plants, such as the presence of a sporopollenin layer and the formation of complex structures like multicellular sex organs. In terms of classification, charophytes belong to the Charophyceae class within the green algae, which also includes other freshwater green algae outside the charophyte group.
