Cell Transport

Front

What is cell transport?

Back

Cell transport refers to the movement of substances into and out of cells, which is essential for maintaining homeostasis and allowing cells to function properly.

Front

What is the cell membrane?

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment. It regulates what enters and leaves the cell.

Front

Define isotonic solution.

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

Define 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 and potentially leading to swelling or bursting.

Front

Define 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 and potentially leading to shrinkage.

Front

What is passive transport?

Back

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

Front

What is active transport?

Back

Active transport is the movement of substances against a concentration gradient, requiring energy (usually in the form of ATP) to occur.

Front

What is osmosis?

Back

Osmosis is the passive transport of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is facilitated diffusion?

Back

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

Front

What are constants in an experiment?

Back

Constants are the factors that are kept the same throughout an experiment to ensure that the results are due to the independent variable.
