Front

How is food moved into the cell?

Back

Endocytosis

Front

What process allows water to move into root cells of a plant when the concentration of water is higher in the soil?

Back

Osmosis

Front

What happens to water when a cell is placed in a hypertonic solution?

Back

Water moves from the inside of the cell to the solution.

Front

What type of cell transport is represented by the process of a cell engulfing material?

Back

Endocytosis

Front

Define diffusion.

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the main difference between active transport and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is facilitated diffusion?

Back

The process of transporting molecules across a membrane via protein channels without energy.

Front

What occurs during exocytosis?

Back

The process by which a cell expels materials in vesicles.
