There are several groups, including the reds (which include many seaweeds, including the coralline algae), greens (that include both marine, aquatic and terrestrial species, and are related to land plants), [ and the browns (which also include many seaweeds, including kelp). They are in the protista kingdom. They were first in the plantae kingdom and have moved a lot and been disputed about, but they have been decided to be in the protista kingdom. ]
presence of chlorophyll a for carrying out photosynthesis
name two unicellular algae
Microscopic green algae from the class Prasinophyceae have recently been recognized as major constituents of oceanic phytoplankton.

There are THREE major protists groups. Before, there were classified in two groups. This are the one: PROTOZOA ALGAE FUNGUS-LIKE FUNGI PROTISTS
Chlamydomonas reinhardtii is in nature largely photoautotrophic (obtaining all its energy from photosynthesis). However, it can grow heterotrophically when supplied with a suitable carbon source (acetate is commonly used). This is quite an artificial situation, but allows it to be grown in laboratories in the dark, and to grow mutants which are unable to perform photosynthesis.
phytoplankton
Diatoms are eukaryotic, they are a major class of algae and the most common type of phytoplankton. They are unicellular yet exist in colonies in the shape of ribbons.
Absorbing Dissolved Nutrients
Sponges are neither protostomes nor deuterostomes. They have no mouth and no anus, one of the major distinguishing features of both proto./ deutero. is that they have both an anus and a mouth formation.
The key features of plant kingdom are:-These organisms are eukaryote and mostly autotrophs. These are unicellular to multicelluar organisms with cellulosic cell wall. Reproduce by both sexual and asexual means. Their cells are totipotant (i. e. have power of regeneration)

Microscopic green algae from the class Prasinophyceae have recently been recognized as major constituents of oceanic phytoplankton.
1) Zooflagellates swim with flagella 2) Sarcodines move by extensions of their cytoplasm 3) Ciliates move by means of cilia 4) Sporozoans do not move on their own at all.
Seaweeds are classified into three major groups; the green algae, the brown algae, and the red algae. Placement of seaweed into one of these groups is based on the pigments and colouration existing in the plant. Other seaweed features that are used to classify algae include: cell wall composition, reproductive characteristics, and the chemical nature of the photosynthetic products. Plant structure, form and shape are additional characteristics used to classify seaweed.
