6CO2 + 6H2O > C6H12O6 + 6O2
Carbon dioxide + water > glucose + oxygen
However, this is a massive over simplification, and there are actually many things happening in-between the products and reactants.
Photosynthesis is a series of reactions that take place in the chloroplast of leaf cells, these reactions are split into two stages: the light dependent and the light independent.
- Wax cuticle lets light in but stops too much water from being lost
- Palisade cells are long to increase the chances of sunlight hitting the chlorophyll that they contain
- Spongy mesophyll has air gaps for quick gas exchange
- Vascular bundle (xylem (and phloem) brings water to the reaction
- Stomata allows CO2 in but doesn't let too much water out
- Leaves are thin so the diffusion distance is small and the SA for catching light is big
- The chloroplast envelope- double plasma membrane to control the movement of substances in and out
- The grana- stacks of disks (thylakoids) which contain chlorophyll and have a large surface area for the first stage of photosynthesis.
- Interlamellae link gramun so that ions can be transported between them.
- The stoma- matrix with the enzymes needed for the second stage of photosynthesis
- DNA and ribosomes to manufacture proteins for photosynthesis
