- Photosynthesis
- Plants make their own food by photosynthesis
- C02+H20 ----> Glucose + O2
- It is how plants make food which is glucose.
- Happens in the leaves of green plants
- Happens inside chloroplasts
- They contain chlorophyll which absorbs energy in sunlight
- Leaves are Adapted for Photosynthesis
- Broad meaning they have a large surface area.
- They contain lots of chlorophyll in chloroplasts to absorb light.
- They are full of holes called stomata.
- Open and close to allow C02 in and 02 out.
- Also allow water vapor to escape.
- Limiting factor depends on the conditions
- The rate is affected by...
- Light intensity
- Limiting factor - Stops photosynthesis going any faster.
- Temperature
- Limiting factor - Stops photosynthesis going any faster.
- The concentration of CO2
- Limiting factor - Stops photosynthesis going any faster.
- Temperature
- Limiting factor - Stops photosynthesis going any faster.
- Light intensity
- Which factor is limiting at a particular time changes.
- At night it is light
- In winter, it can be temperature
- C02 is limited if warm and bright.
- The rate is affected by...
- Plants make their own food by photosynthesis
