​Protists= Heterotrophs (or) Autotrophs

Heterotrophic protists include:

​Phagotrophs= Uses the body to swallow up surrounding nutrients

​Osmotrophs= Absorbs surrounding nutrients

​Phagotrophs are not fruit

​Protist nutrition

​

​Protists are a source of terrible illnesses that ravage humanity, finding out how these protists get nutrients is one step closer to getting rid of these diseases.

​We want to starve bad protists.

​Protist Nutrition Importance

​

​Protists also affect the environment.

​-Studies estimate that algae are responsible for 50% of the world's photosynthesis

-Aquatic protists are responsible for keeping various bacteria species numbers in check​

​

​Kelp are aquatic protists.

​Protist Nutrition Importance cont.

​

Scientists often argue on protist classification

​-Scientists have moved away from

​classification based on morphology and now onto genetic similarities

-Protists aren't one family, they have been split into many categories on a family tree​
