- The leaves are the organs of photosyntheses. They make all the food that the plant needs.
- Leaves contain chlorophyll which uses light energy to change CO2 and water into glucose.
- They have tiny little pores which allow essential CO2 in, and waste gases out- there are no lungs.
- So leaves are really important for nutrition and excretion.
