How do protists move?

Back

Protists can move using various structures such as cilia, flagella, or pseudopods.

Front

What are cilia?

Back

Cilia are short, hair-like structures that protrude from the surface of some protists and help them move by beating in a coordinated manner.

Front

What are pseudopods?

Back

Pseudopods are temporary projections of a cell's cytoplasm that help some protists move and capture food.

Front

What is a flagellum?

Back

A flagellum is a long, whip-like structure that some protists use for movement.

Front

How do protists obtain food?

Back

Protists can obtain food through various methods, including photosynthesis, absorption, and engulfing food particles.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which some organisms, including certain protists, convert light energy into chemical energy to produce food.

Front

What is a food vacuole?

Back

A food vacuole is a membrane-bound sac within a cell that contains food particles engulfed by the cell.

Front

What is an organ?

Back

An organ is a group of tissues that work together to perform a specific function in an organism.

Front

What is a tissue?

Back

A tissue is a group of similar cells that work together to perform a specific function.
