Biology: Cell Transport

Front

What is Active Transport?

Back

The cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration, requiring energy.

Front

Define Equilibrium in a biological context.

Back

A state reached when particles continue to move back and forth but neither side has more particles than the other.

Front

How do cell walls protect plant cells from swelling?

Back

Cell walls keep plant cells from swelling too much when water is absorbed, maintaining structural integrity.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is Exocytosis?

Back

The process by which large particles, cell products, or waste are released to the outside of the cell.

Front

What is Diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration without the use of energy.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy, including processes like diffusion and osmosis.

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is Homeostasis?

Back

The process by which living organisms maintain a stable internal environment despite changes in external conditions.
