Mitosis and Cell differentiation

What is diffusion?

The movement of particles from an area of high concentration to an area of low concentration

Give an example of diffusion?

When a fragrance gets spray it diffuses through the air until evenly spread

What is osmosis?

the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration

What is a hypertonic solution?

A solution in which cells have a higher water potential than the solution. Shriveled cells

What is an Isotonic solution?

A solution in which the water potential is equal between cells and solution

What is a hypotonic solution?

A solution in which cells have a lower water potential than the solution. Cells swell

What is active transport?

the movement of molecules across a cell membrane from an area of low concentration to an area of high concentration, against the concentration gradient, requiring energy

What does active transport require?

energy in the form of ATP
