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.Learn More
Three interesting facts about the Kingdom Protista are that all members are eukaryotic, they are not plants, animals or fungi and they are usually single celled. Living things that do not fit into any other Kingdom are classified in this Kingdom and are called protists.Full Answer >
The cell membrane is a flexible membrane that surrounds all eukaryotic cells. The membrane holds all of the organelles inside of the cell and keeps certain solutes from coming into or leaving the cell.Full Answer >
Cell membranes contain and protect the contents of the cell. They are active in signaling other cells, and proteins embedded in their matrix regulate the cell's chemistry by selectively absorbing and secreting chemicals. Many single-celled organisms, such as amoebae, use their flexible membranes for locomotion and food gathering.Full Answer >
A cell membrane is a thin layer that acts as a barrier that separates an individual cell or a cellular compartment from other surrounding structures. This dynamic layer plays an essential part in the transport of ions and nutrients.Full Answer >
