* The term "protist" is derived from the Greek protiston‚ meaning the "first of all ones." * Individual protists tend to be quite small‚ either unicellular or an undifferentiated multicellular mass. At one point‚ "Protista" encompassed everything that wasn’t an animal or plant‚ until the advent of cellular biology which noted fundamental differences between bacteria and the rest of life. * Now bacteria are a separate category from protists.

of the Protist known as Tetrahymena vorax Abstract The purpose of this experiment was to study the rate of phagocytosis of the specific protist known as Tetrahymena vorax. This certain kind of protist feeds at a normal rate when conditions are normal. We began the experiment of understanding how Tetrahymena feeds at normal temperatures. Doing so‚ we allowed the Tetrahymena to feed at specific time limits and then killed the protist with gluderaldheyde to detect how much the protist gained

Then they are split based on their form of locomotion. * They live in moist environments -> aquatic environments or blood. * Even though they are single-celled‚ they are MUCH larger than Archae and bacteria (refer

proton "first" and ζῷα zoa "animals"; singular protozoon) are microorganisms classified as unicellular eukaryotes.[1] While there is no exact definition of the term "protozoan"‚ most scientists use the word to refer to a unicellular heterotrophic protist‚ such as an amoeba or a cilipoopate. The term algae is used for microorganisms that photosynthesize. However‚ the distinction between protozoa and algae is often vague. For example‚ the alga Dinobryon has chloroplasts for photosynthesis‚ but it can

Diatoms exist as single cells‚ although some of them flock together in colonies that create some really pretty forms. Each individual cell is covered in a hardened frustule made from silica. They are both alike in that they are both protists. However‚ dinoflagellates are a part of a group called alveolates. They are most common in marine and freshwater phytoplankton. Some are heterotrophic. Diatoms‚ on the other‚ are a part of a group called stramenopiles. They are unicellular

Protist- a protest is a eukaryote that is not a member of the plant‚ animal‚ or fungi kingdom b. compare the updated classification of protists with the older one. Recently the protest kingdom has been divided into six major clades. These new found clades relate some of the protists to animals and fungi. 2.What are the four major ways protists can move?
