Tonicity and Osmosis

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation.

Front

What is the difference between active and passive transport?

Back

Passive transport is the movement of substances from high to low concentration without using energy, while active transport moves substances from low to high concentration using energy.

Front

What is another word that can be used to describe 'homeostasis'?

Back

STABLE

Front

What type of solution allows water to enter the plant cell?

Back

Hypotonic solution.

Front

What will happen to a cell in a hypotonic solution?

Back

The cell will swell up.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

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.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while restricting the movement of solutes.
