- the process that produces FOOD in plants and algae. The food is GLUCOSE
- happens in chloroplasts, which contain chlorophyll (green substance) - absorbs sunlight, uses energy to convert carbon dioxide and water into glucosee. Oxygen may also be produced
- happens in leaves of all green plants.
4 raw materials needed for photosynthesis:
1. sunlight: beating down on leaf provides energy for the process
2. chlorophyll: contained in chloroplasts
3. water: reaches the cells by the xylem
4. carbon dioxide: diffuses into the leaf
the epidermis are located at the top and bottom of the leaf, allowing carbon dioxide and oxygen to diffuse through, the mesophyll is located in the middle of the leaf between the epidermis.
