What are protists?

Back

Protists are a diverse group of eukaryotic microorganisms, which can be unicellular or multicellular, and are not classified as animals, plants, or fungi.

Front

What is the main difference between autotrophic and heterotrophic protists?

Back

Autotrophic protists can produce their own food through photosynthesis (e.g., Euglena, Volvox), while heterotrophic protists obtain food by consuming other organisms.

Front

What are the two main types of protists?

Back

The two main types of protists are plant-like protists (e.g., algae) and animal-like protists (e.g., protozoa).

Front

What is Euglena known for?

Back

Euglena is known for being both autotrophic and heterotrophic, possessing chloroplasts for photosynthesis and the ability to consume food.

Front

What are pseudopods?

Back

Pseudopods are temporary, foot-like extensions of a cell used for movement and feeding, commonly found in amoebas.

Front

What is the function of cilia in protists?

Back

Cilia are fine hair-like structures that help protists move and feed by creating water currents.

Front

What is the oral groove in Paramecium?

Back

The oral groove is a specialized structure in Paramecium that helps in the intake of food.

Front

What is the gullet in Paramecium?

Back

The gullet is a tube-like structure in Paramecium that leads to the food vacuole, where food is digested.

Front

What is Volvox?

Back

Volvox is a type of green algae that forms spherical colonies and is known for its ability to perform photosynthesis.

Front

How do protists reproduce?

Back

Protists can reproduce both sexually and asexually, depending on the species and environmental conditions.
