Photosynthesis
- Plants make their own carbon-compounds through the process of photosynthesis
- During photosynthesis energy from sunlight is absorbed by chlorophyll, a green pigment found inside chloroplasts
- The light energy is used to convert carbon dioxide and water into glucose
- Oxygen is made and released as a waste product
- The chemical reactions of photosynthesis are catalysed by enzymes
Photosynthesis word equation
How do plants use the glucose produced during photosynthesis?
- The glucose can enter respiration, releasing energy for the plant
- Glucose can also be converted to other carbon-compounds, e.g.
- Starch for storage
- Cellulose for building cell walls
- Amino acids which are used to build plant proteins
- Lipids, such as the oils used to store energy inside seeds
