osmosis & tonicity

The movement of any substance directly through the cell membrane with no energy

Diffusion

Osmosis does not need this to occur

ENERGY

In these solutions there is a higher concentration of water INSIDE the cell than OUTSIDE the cell

Hypertonic

In these solutions there is a higher concentration of water OUTSIDE the cell than INSIDE the cell

Hypotonic

The diffusion of water across the membrane using no energy and a specialized pore, aquaporin, is called

Osmosis

This describes the membranes ability to control what enters and exits the cell

Semi-permeability

In a hypertonic solution the cell

Shrinks

In a hypotonic solution the cell

Swells

A solution with a higher SOLUTE concentration that the inside of a cell is_______.

hypertonic because there is less water in the solution

A solution with a lower SOLUTE concentration than the inside of a cell is _________.

hypotonic because there is more water in the solution

The shrinking of a plant cell exposed to a hypertonic solution is called

plasmolysis

When an animal cell is placed in a hypotonic solution and absorbs too much water _________happens.

plasmolysis
