Front

What are the two kinds of passive transport?

Back

Diffusion and osmosis.

Front

What are the two kinds of active transport?

Back

Engulfing and transport proteins.

Front

During passive transport, molecules move from an area of ______ concentration to an area of _____ concentration.

Back

higher, lower.

Front

In a freshwater solution, the concentration of water will be ______ inside a cell, which will cause water to ______.

Back

lower, come in to the cell.

Front

What is the diffusion of water called?

Back

Osmosis.

Front

Define diffusion in the context of cell transport.

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 role do transport proteins play in active transport?

Back

They help move substances across the cell membrane against their concentration gradient.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and may shrink.
