Plant–like protists are called as algae
All the photosynthetic protists account for over 80 per cent of the carbon dioxide fixed in the biosphere.
The plant–like protists are abundantly found in both fresh water and sea water.
All of the plant – like protists called as algae. Algae is a term that can be used to refer to almost all chlorophyll–bearing organisms found living in water. Many of the various algae are members of the protist kingdom, while others are members of the plant kingdom.
There are three main groups of photosynthetic protists. They are the euglenophytes, the chrysophytes and the pyrrophytes. The euglenophytes include euglenoids such as Euglena. The chrysophytes include diatoms and golden algae. The pyrrophytes include the dinoflagellates.
Importance of plant – like protists: All the photosynthetic protists account for over 80 per cent of the carbon dioxide fixed in the biosphere. The plant–like protists are abundantly found in both fresh water and sea water. As photosynthetic organisms, the plant–like protists use light and simple inorganic materials to make their food and to produce oxygen. These plant–like protists along with other kinds of algae maintain over half of the earth's oxygen supply. They are the most important primary producers. The primary producers make the main source of food–either directly or indirectly–for all animals of the sea and shore. Nevertheless, they are so important; the earth would be unable to support life without them.
