Cellular Transport

Front

What is the main difference between passive and active transport?

Back

Active transport uses energy, while passive transport does not.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What controls the movement of substances into and out of the cell?

Back

The cell membrane controls the movement of substances into and out of the cell.

Front

Which process is NOT a type of passive transport?

Back

Exocytosis is NOT a type of passive transport.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is facilitated diffusion?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What is the role of the cell wall?

Back

The cell wall provides structure and protection to plant cells, but it does not control movement of substances.
