Question

Match the following

Column 1	Column 2
Taken from air for photosynthesis	Chlorophyll
Necessary for respiration	Alcohol
Capture sunlight	Carbon dioxide
Anaerobic respiration	Oxygen
Guard cells	Stomata

Answer 1

A. Taken from air for photosynthesis III. Carbon dioxide

1. Carbon dioxide is an essential raw material for photosynthesis.
2. It is absorbed from the atmosphere through the stomata of leaves.

B. Necessary for respiration IV. Oxygen

1. Oxygen is necessary for respiration.
2. Oxygen helps in the breakdown of glucose into carbon dioxide and water.

C. Capture sunlight I. Chlorophyll

1. Chlorophyll is the green pigment which is found in the chloroplast of leaves.
2. It captures sunlight during photosynthesis.

D. Anaerobic respiration II. Alcohol

1. If the breakdown of food occurs in absence of oxygen, it is called anaerobic respiration.
2. The products formed during anaerobic respiration are Alcohol, carbon dioxide and 2 moles of ATP.

E. Guard cells V. Stomata

1. Stomata is a special structure found in leaves which contains a minute pore called stoma and two guard cells.
2. Stomata help in the passage of oxygen and carbon dioxide during photosynthesis and respiration.
3. Guard cells control the opening and closing of stomata.
