Water, sunlight, carbon dioxide and chlorophyll are necessary for photosynthesis to occur.
Chloroplast!!!! http://en.wikipedia.org/wiki/Chloroplast
No chlrophyll manufactures food (glucose) by photosynthesis
Spindle Fibers
Water is a reactant in photosythesis that is a liquid.
An acid and a base
Isolation Is necessary for speciation to occur.
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
glucose
Sunlight
Photosynthesis requires energy from light. If there is no light there can be no photosynthesis. Photosynthesis doesn't occur in the dark. You could use electric lights to simulate daylight and make plants photosynthesise during the night time.
