carbon dioxide + water
Photosynthesis =light energy=>
glucose + oxygen

Chlorophyll a green substance found in chloroplasts which absorbs light energy

Carbon dioxide and Water these substances are converted into glucose

Oxygen by-product of photosynthesis

Limiting factors light intensity,temperature and concentration of carbon dioxide

this provides energy needed for photosynthesis causing rate to increase
Light intensity
up to a certain point at which rate ceases to increase

this is needed for photosynthesis causing rate to increase up to a certain
Carbon dioxide level
point at which rate stops increasing

this effects the speed a which enzymes work if enzymes are denatured
Temperature
by high temperature then rate will decrease

Respiration glucose is used for this process as a way of releasing energy

Cellulose glucose is used to make this substance which is found in the cell wall of plant cells

Proteinsynthesis glucose is used to make amino acids for making proteins

glucose is converted into lipids, which are stored in seeds and cells, and
Glucose storage
starch, which are stored for later use in roots and stems
