What is the stiff, protective outer layer of plant cells called?

Back

The cell wall is the rigid outer layer that provides support and protection to plant cells.

Front

What is the function of the Golgi body?

Back

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane using energy, usually against a concentration gradient.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many metabolic processes.
