FLASHCARD QUESTION

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.

2.

FLASHCARD QUESTION

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.

3.

FLASHCARD QUESTION

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.

4.

FLASHCARD QUESTION

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.

5.

FLASHCARD QUESTION

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.

6.

FLASHCARD QUESTION

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.

7.

FLASHCARD QUESTION

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.
