Amoxicillin, penicillin, and erythromycin are common antibiotics that inhibit bacterial cell functions. Antibiotics are derived primarily from bacteria or fungi (mold), such as Penicillium. Antibiotics don’t work exclusively against bacteria: some ‘broad-spectrum’ ones are also effective against protists.

Where do protists live?

What are the 3 categories of protists?

Protists are defined by how they obtain nutrition and how they move. Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.

What are 5 ways protists help us?

Protists produce almost one-half of the oxygen on the planet through photosynthesis, decompose and recycle nutrients that humans need to live, and make up a huge part of the food chain. Humans use protists for many other reasons: Many protists are also commonly used in medical research.

What is a beneficial protist?

Where do protists come from?

The protists are thought to have arisen from bacteria, with symbiotic associations being involved in some way. Some researchers have hypothesized that the first protists were of a nonpigmented heterotrophic form. From within the vast array of protists, there must have arisen the early eukaryotes.

How do protists affect humans?

Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
