The leaf support should actually be water. if in hot and dry weather, the leaf loss so much water that will make the plant cells flaccid and wilt.
Photosynthesis is the chemical process used in plants to convert energy in the form of sunlight into chemical energy in the form of sugar or other carbohydrates.
<span><span>General equation:<span><span>carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water</span><span>CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O
</span></span></span><span>Net equation: Because glucose, a six carbon sugar, is often an intermediate product of photosynthesis, the net equation is frequently written as:</span></span>carbon dioxide + water + light energy ==> glucose + oxygen + water<span>6CO2 + 12H2O + Light Energy ==> C6H12O6 + 6O2 + 6H2O</span><span>Balanced equation: The net equation above can be simplified as:<span><span>6CO2 + 6H2O + Light Energy </span>==><span> C6H12O6 + 6O<span>2</span></span></span></span>
