- Photosynthesis
- Plant organs
- Made of tissues
- Stems
- Roots
- Leaves
- Leaves
- Leaves
- Mesophyll tissue
- Where photosynthesis occurs
- Xylem & Phloem
- Transports water,mineral ions and sucrose
- Epidermal tissue
- Covers the whole plant
- Carbon dioxide+water > glucose + oxygen
- Sunlight on leaf provides energy
- Chrolophyll is in chloroplasts
- Water reaches the cell via the xylem
- Carbon Dioxide diffuses into the leaf
- Produces glucose using sunlight
- Limiting factors- stop photosynthesis happening faster
- Light
- Change light intensity by moving the lamp
- Use a light meter to improve the results
- Change light intensity by moving the lamp
- Carbon dioxide
- Dissolving hydrogencarbonate controls Carbon dioxide levels
- Temperature
- Above 45 degrees enzymes denature
- Control temperature using a water bath
- Above 45 degrees enzymes denature
- Light
- Ideal conditions can be artificially created
- Limiting factors- stop photosynthesis happening faster

- Temperature
- Above 45 degrees enzymes denature
- Control temperature using a water bath
- Above 45 degrees enzymes denature
- Light
- Heater
- Paraffin heater
- Artificial lighting
- Money not wasted
- Limiting factors- stop photosynthesis happening faster
- How a plant uses glucose
- For respiration
- Making cell walls
- Making proteins
- Stored in seeds
- Stored as starch
- Plant organs
