(a) Photosynthesis is process in which certain
carbohydrates are synthesized from carbon dioxide and water by chlorophyllous cells in the presence of light, oxygen being a bys product. The summary equatios repréàinting the process of photosynthesis is conventionally written as follows:

The conditions necessary for tab. procese of photosynthesis äre: (1) light mast bé present; (11) Chlorophyll must be present; (iii) carbon dioxide must be available; and (1v) oxygen must be evolved.

merobic respiration 18 an oxidatims process which occurs in the presence of sxygsh. During this process, the intake öxygen combines with the carbon of the carbohydrate, đó tổàt the products of the process are carbon dioxide and water.-In other words, there is ên, antiye brèslitown of the carbohydrate and complete liberation of energy.
