The spreading out of particles from an area of higher concentration to an area of lower concentration.

Osmosis
The diffusion of water molecules across a partially permeable membrane from a dilute solution to a more concentrated solution.

Active Transport
The movement of substances against a concentration gradient, requiring energy from respiration.

Mitosis
A type of cell division that produces two genetically identical daughter cells for growth and repair.

Pathogen

Enzyme
A biological catalyst that speeds up the rate of a chemical reaction without being used up.

Photosynthesis
The process by which green plants and algae use light energy to convert carbon dioxide and water into glucose and oxygen.
Equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Respiration
The process of transferring energy from the breakdown of glucose, which occurs in every living cell.
