Answers
(a) Photosynthesis: Photosynthesis is the process by which living plant cells, containing chlorophyll, produce food substances (glucose and starch), from carbon dioxide and water, by using light energy and release oxygen as a by-product.
(b) Thylakoids: Closely packed flattened sacs arranged in piles in the interior of chloroplasts are called thylakoids.
(c) Chloroplast: Chloroplasts are minute oval bodies bounded by a double membrane which contains thylakoids arranged in piles called grana lying in a colourless ground substance called stroma.
(d) Photolysis of water: Photolysis of water is defined as the splitting of H2O molecules into hydrogen ions and oxygen in the presence of light.
(e) Polymerisation: Polymerisation is the process in which several glucose molecules are transformed to produce one molecule of starch.
