Cell Transport

Front

What is an isotonic environment?

Back

An isotonic environment is one where the concentrations of water are equal inside and outside the cell.

Front

What is required for the movement of materials from low concentration to high concentration?

Back

The movement of materials from an area of low concentration to an area of high concentration requires energy (ATP).

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, such as baking cookies and smelling them throughout the house.

Front

What is endocytosis?

Back

Endocytosis is a process in which cells surround and engulf substances that are too big to enter the cell.

Front

What is dynamic equilibrium in relation to cell transport?

Back

Dynamic equilibrium is the state when material passes into and out of a cell at equal rates, with no difference in concentration between the inside and outside of the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a semi-permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is pinocytosis?

Back

Pinocytosis is a type of endocytosis where the cell engulfs liquid substances.

Front

What is phagocytosis?

Back

Phagocytosis is a type of endocytosis where the cell engulfs large particles or cells.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain substances to pass while blocking others.
