Cell 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, potentially leading to swelling or bursting.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration across a semi-permeable membrane.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to leave the cell, leading to shrinkage.

Front

What is active transport?

Back

Active transport is the process by which cells use energy to move materials against their concentration gradient, from low to high concentration.

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 molecules spread from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

What is facilitated diffusion?

Back

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

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 and allowing for selective permeability.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the cell, which may cause the cell to swell and potentially burst.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the cell, causing the cell to shrink and lose turgor pressure.
