Question

Considering a leaf as a factory, match the items in column A with column B.

COLUMN A	COLUMN B
(i) Sunlight	(a) End product
(ii) Carbon dioxide and water	(b) Power
(iii) Chloroplast	(c) Raw materials
(iv) Glucose	(d) Work station

• A. (i) – (b); (ii) – (c); (iii) – (d); (iv) – (a)
• B. (i) – (c); (ii) – (d); (iii) – (a); (iv) – (b)
• C. (i) – (c); (ii) – (b); (iii) – (d); (iv) – (a)
• D. (i) – (b); (ii) – (c); (iii) – (a); (iv) – (d)

Answer 1

The correct option is A (i) – (b); (ii) – (c); (iii) – (d); (iv) – (a)

Photosynthesis is the process by which green plants produce their food, i.e., glucose (the end product of photosynthesis). For the production of food, plants require the raw materials carbon dioxide and water. They prepare the food in the work station, i.e., the chloroplasts present in the leaves, as they have the pigment chlorophyll that helps plants capture sunlight, which is the source of power for the process.
