An outline of photosynthesis:
- 6CO2 + 6H20 -> 6O2 + C6H12O6
- Carbon dioxide + water -> oxygen and glucose
- Process of energy transferral in which some of the energy in light is conserved in the form of chemical bonds
- Site of photosynthesis:
- Leaf - main photosynthetic structure
- Chloroplasts - cellular organisms within leaf where photosynthesis takes place
Structure of the leaf:
- Adapted to bring together the three raw materials of photosynthesis - water, carbon dioxide and light
- Removes the products - oxygen and glucose
Adaptations:
- Large surface area - absorbs as much sunlight as possible
- An arrangement of leaves on the plant - minimises overlapping and so avoids the shadowing of one leaf by another
- Thin - most light is absorbed in the first micrometer of the leaf and the diffusion distance for gases is kept short
- A transparent cuiticle and epidermis - let light through to the photosynthetic mesophyll cells beneath
- Long, narrow upper mesophyll…
