Chlorophyll--A green substance which gives leaves their color. Chlorophyll absorbs energy from sunlight which a plant uses to make food.

Chloroplast--A plastid that contains chlorophyll and is the site where photosynthesis and starch formation occur.

Photosynthesis--The formation of carbohydrates (sugars) in the chlorophyll-containing tissues of plants exposed to light.

Stomata--A very small hole in the surface of a leaf. Oxygen and carbon dioxide from the air enter through the stomata; oxygen, carbon dioxide and water vapor leave through the stomata.

Diffusion: is the tenancy of particles in a gas or liquid to become evenly distributed by moving from an area of high concentration to an area of low concentration.

Osmosis: water from the soil enters the root because the concentration of water in the soil is greater than the concentration in the root. Osmosis needs a membrane that selects for different molecules.

Transpiration: is the process that allows water and minerals to move up through the xylem. Transpiration is evaporation through the leaves.

Cellular respiration: the cell process by which food and oxygen are released to the organism.
