Cell Parts and Processes Review

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell, providing a barrier and maintaining homeostasis.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What does selectively permeable mean in relation to the cell membrane?

Back

Selectively permeable means that the cell membrane allows certain substances to pass while blocking others.

Front

What are two examples of passive transport?

Back

Diffusion and Osmosis.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the role of chloroplasts in a cell?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

Front

What is the role of mitochondria in a cell?

Back

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

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a membrane.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane.
