Single-celled organisms that live freely or in small colonies, such as protozoans and algae. Most protists were formerly classified as either animals or plants.
Of the kingdom Protista. Eukaryotic, mostly unicellular organisms, including amoebas, paramecia, and algae.
small, single-celled organisms such as protozoa and some algae.
Single-celled organisms; a type of eukaryote. Protista
often unicellular but they can be multi-cellular or colonial the organisms in this Kingdom have characteristics of plants, animals and fungi and contains most algae
Eukaryotic, mostly single-celled organisms such as diatoms, amoebas, some algae (golden brown and yellow-green), protozoans, and slime molds. Some protists produce their own organic nutrients through photosynthesis. Others are decomposers and some feed on bacteria, other protists, or cells of multicellular organisms.
Protists are single-celled eucaryotic organisms in the Kingdom Protista, also called the Kingdom Protoctista. The five kingdoms in R.H. Whittaker's taxonomic system are the procaryotes (procaryotic organisms, including the bacteria and cyanobacteria), protists, fungi, plants, and animals. "Animal-like" aquatic protists (such as copepods) are often called protozoans or zooplankton. "Plant-like" aquatic protists (such as diatoms) are commonly called phytoplankton. However, the protist biologist Lynn Margulis points out that "these organisms are no more 'one-celled animals and one-celled plants' than people are shell-less multicellular amebas."
A term for members of the kingdom Protista, which includes algae (other than blue-green algae, which are monerans), slime molds (a group of about500 species that resemble fungi), and protozoa.
