What is the cell structure of Protista?

The kingdom Protista consists of unicellular, colonial and multicellular organisms that contain a nucleus enclosed in a membrane. Another organelle found in protists, which are also eukaryotes, is the mitochondria. The protists are subdivided into three categories: plant-like, animal-like and fungi-like protists.

Examples of animal-like protists are amoebas, and plant-like protists are some types of algae and seaweed. Slime mold is an example of a fungi-like protist. Protists can be autotrophs, like the algae that make their own food, or heterotrophs that feed on other organisms.

Protists can move through organelles such as cilia, flagella or pseudopodia. Although most protists reproduce asexually, others are capable of sexual reproduction.

The kingdom Protista contains a very diverse group of organisms. They can range in size from microscopic amoeba to large seaweed.
