Cellular Transport

Front

What is osmosis?

Back

Osmosis is the movement of water from an area of high concentration to an area of low concentration.

Front

What does isotonic mean?

Back

Isotonic refers to a solution where the concentration of solutes is equal inside and outside the cell.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves from the inside of the cell to the outside solution.

Front

What does permeable mean?

Back

Permeable means that substances can pass through a membrane.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which particles move from an area of high concentration to an area of low concentration.

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 move into the cell.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.
