Chloroplasts:
Nuclei, mitochondria, ribosomes and chloroplasts are all called organelles because the all carry out a process

Leaf Structure
Firstly there is the waxy cuticle layer, then the upper epidermis. Next is the palisade layer which is where the majority of photosynthesis occurs because the cells contain a particularly large amount of chloroplasts. Then there is the spongy layer which as well as cells contains air space and the vascular bundle which contains vessels and then the lower epidermis. Finally there are the stoma and the guard cell. The stoma is a tiny pore in the leaf and the guard cell surrounding it controls the entry/exit of substances.
Limiting Factors
A limiting factor is a variable that (when in short supply) can limit the rate of a chemical reaction such as photosynthesis. E.g light intensity, temperature, CO2 concentration
If a leaf had no access to CO2 the leaf would not have starch because if a leaf is missing CO2, light, chlorophyll or water is will not be able to complete phtosynthsis
