What is the function of the cell wall?

Back

It is a thin, flexible membrane that surrounds the cell, maintaining its shape and regulating its interaction with the external environment.

Front

What is simple diffusion?

Back

It is the movement of solutes from an area of high concentration to an area of low concentration without the need for energy.

Front

What is active transport?

Back

It is the movement of solutes from an area of low concentration to an area of high concentration, requiring energy and a carrier.

Front

What is osmosis?

Back

It is the movement of water from an area of low solute concentration to an area of high solute concentration.

Front

What is the chemical structure of the cell wall?

Back

Front

What is cytoplasm?

Back

It is the largest part of the cell that surrounds the nucleus and contains organelles, organic and inorganic compounds, and minerals.

Front

What are food vacuoles?

Back

Small, spherical structures that contain food particles and are involved in digestion, found in simple organisms like amoeba.

Front

What are contractile vacuoles?

Back

Structures that help regulate water balance in some simple organisms, like paramecium, living in freshwater.

Front

What are mitochondria?

Back

Organelles known as the powerhouses of the cell, where energy is produced through the oxidation of nutrients.
