- Photosynthesis
- Green plants and algae use light energy to make their own food. They obtain the raw materials needed from both the air and soil.
- The conditions in which plants are grown will affect the rate of photosynthesis and the rate of growth.
- Equation
- Carbon dioxide + water --- glucose + oxygen
- Light energy is also needed
- Carbon dioxide + water --- glucose + oxygen
- During Photosynthesis
- Light energy is absorbed by chlorophyll
- This energy is used to convert carbon dioxide and water into glucose
- Oxygen is released as a by product
- This energy is used to convert carbon dioxide and water into glucose
- Light energy is absorbed by chlorophyll
- Limiting Factors
- Light
- Temperature
- Carbon dioxide
- Enhancing these factors in greenhouses will produce better yields
- Using the Glucose
- Glucose produced in photosynthesis may be converted into insoluble starch for storage or growth
- Plant cells use some of the glucose straight away for processes such as respiration
- It can also be used to produce...
- Fat or oil for storage
- Cellulose
- Proteins (nitrate ions are also used to produce these)
- Green plants and algae use light energy to make their own food. They obtain the raw materials needed from both the air and soil.
