They do not have roots, stems, or leaves
Edited answer:
Algae come under primitive plants as these ahve varity of forms ranging from unicellular to multicellular colonial and filamentous and have undifferentiated body.
Because they are plants.
Trees have sex and algae jerks off! :)
Algae are plants.
Plants are the ancestors of seaweeds. Convergent evolution caused their similarity. Both evolved from brown algae. Seaweeds are the ancestors of plants. Seaweeds are aquatic plants.
The major difference between plants and algae is that plants have connective tissues for the transportation of water in the entire plant body while every cell of algae absorbs water from the source on its own. There is no connective tissue is algae. Secondly, the reproduction system of plants is more developed while that of algae is primitive. Thirdly, algae can be single-celled while plants are multicellular organisms. Another area of difference between plants and algae is photo respiration. Moreover, it is argued by the scientists that algae and plants may share the same ancestor but algae cannot be classified as plants.
both contain chlorophyll11 but plants are differentiate between stem,roots & leaves and algae can not be differentiate between stems,roots ant leaves.
The difference between algae and angiosperms is angiosperms have true roots,stems and leaves while algae does not. Also angiosperms are flowering plants and algae lives mainly in water.

Both algae and seed plants have cells with chloroplasts.
Green algae use each cell to absorb water directly from the source while plants have connective tissue that transport water from the source to all of its parts. The other difference is that plants are multicellular and green algae do have single cells.
Protozoa move while algae do not.
Algae is harmful to people and animals depending on season Seaweed is a type of algae.
bacteria is a prokaryote while algae is a eukaryote
Algae are simple plants. The biggest similarity with more 'regular' lants is that they both contain chlorophyll Green algae and plants are sister taxon, that is, they share a common ancestor. For this reason, they both have double membrane bound plastids that contain chlorophyll a and b. Their main storage compound is starch, and they use cellulose to build their cell walls. There are other similarities involving the arrangement of microtubules associated with the flagella; however, these can only be seen using a transmission electron microscope.
