Back

The vacuole stores food, water, and waste in a cell.

Front

What type of cellular transport is exocytosis?

Back

Exocytosis is a process where materials are expelled from the cell.

Front

What happens to the cell membrane when a plant cell loses water?

Back

The cell membrane shrinks while the cell wall remains the same.

Front

What is the cytoskeleton?

Back

The cytoskeleton is an internal network of tubes that helps the cell maintain its shape and assists in cell division.

Front

What does the fluid mosaic model describe about the cell membrane?

Back

The fluid mosaic model describes the cell membrane as a flexible pattern made up of different parts.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in a cell.

Front

What is the difference between endocytosis and exocytosis?

Back

Endocytosis is the process of taking materials into the cell, while exocytosis is the process of expelling materials from the cell.

Front

What is the function of the cell wall?

Back

The cell wall provides structure and protection to plant cells.
