The Cell in Action Study Guide

What is Passive Transport?

Back

Passive transport is the movement of particles from an area of high concentration to an area of low concentration without the use of energy.

Front

What is Active Transport?

Back

Active transport is the movement of particles from an area of low concentration to an area of high concentration using energy.

Front

What is the Cell Cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and mitosis.

Front

What is Mitosis?

Back

Mitosis is the process by which a cell divides its nucleus and genetic material to form two identical daughter cells.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that occurs after mitosis, where the cytoplasm of a parent cell divides into two daughter cells.

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.

Front

What is Diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration without energy.

Front

What is Osmosis?

Back

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

Front

What is the role of energy in Active Transport?

Back

Energy is required in active transport to move particles against their concentration gradient.
