Cell Transport

Front

What is Endocytosis?

Back

Endocytosis is the process by which a cell membrane surrounds a particle and encloses it, allowing large particles to enter the cell.

Front

What is the function of the cell membrane?

Back

The cell membrane helps maintain homeostasis by controlling what substances may enter or leave the cell.

Front

What are the two types of cell transport?

Back

The two types of cell transport are Passive transport and Active transport.

Front

What is Passive transport?

Back

Passive transport is the movement of materials across a cell membrane without using energy, typically moving from high to low concentration.

Front

What are two examples of passive transport?

Back

Two examples of passive transport are Diffusion and Osmosis.

Front

What is Active transport?

Back

Active transport is the movement of materials against a concentration gradient, requiring energy.

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 is Osmosis?

Back

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

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane.
