NEET BIOLOGY

Detailed explanation-1: -Protists can look very different from each other. Some are tiny and unicellular, like an amoeba, and some are large and multicellular, like seaweed.

Detailed explanation-2: -Protists are mostly unicellular (one-celled) eukaryotes. A few protists are multicellular (many-celled) and surprisingly large.

Detailed explanation-3: -Although most protists are single-celled, protists like kelp (brown algae) can grow over 100 meters. Therefore, not all protists are unicellular.

Detailed explanation-4: -Most protists are microscopic and unicellular, but some true multicellular forms exist. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism.

Detailed explanation-5: -Protists are typically unicellular organisms, though some are multicellular. They live in a variety of aquatic environments, and some are also found in moist soil. Some protist species are parasites and are responsible for a variety of major human diseases such as malaria, toxoplasmosis, and trypanosomiasis.
