I ran an experiment by getting three leaves from different trees/bushs and putting them in a dark room. My hypothosis was nothing would happen. After a 10 minutes I came up with these results... hypothosis was correct, nothing happened. New test, same hypothosis. Put in a plasic container for 10 minutes in a dark room. Results.... hypothosis was correct, nothing happened. New test, New hypothosis. Put in a plasic container filled with water for 10 minutes in a dark room. The leaves will recover from their drier state and become moist again. Note these leaves were picked from trees less than an hour ago. Results... hypothosis was correct, The leaves became drier and more firm, and slightly heaver,Though this effect had nothing to do with putting it in a dark room. I ran this experiment just becase I was bored. Stop asking these stupid questions.

Why the leaves of plant kept in dark do not produce starch?
A leaf needs light energy to photosynthesise. The way it can obtain this energy is from a light source, and the dark has no light sources-so the leaf cannot obtain light energy, it cannot photosynthesise. This process involves producing starch (as glucose is made, then converted into starch) and so no photosynthesis=no starch.
