Question

18.Massive amounts of gaseous exchange takes place in the leaves through stomata for the

purpose of

(a) Photosynthesis

(b) Carrying carbon dioxide

(c) Reduction of carbon dioxide

(d) Generation of carbohydrate​

Answer 1

Answer:

photosynthesis

Explanation:

Gas exchange allows plants to absorb CO2 and release O2

Answer 2

Massive amounts of gaseous exchange takes place in the leaves through stomata for the  purpose of  Photosynthesis

Explanation:

• Plants obtain the gases they require through their leaves.
• For respiration, they need oxygen, and for photosynthesis, they need carbon dioxide.
• Gases enter the intercellular spaces of the leaf through holes called stomata, which are generally found on the underside of the leaf.
• Gaseous exchange occurs by stomata diffusion.
• Each stomata is controlled by guard cells.
• The shutting and opening of the stoma between the inferior leaves and the atmosphere results in gas exchange.
• In the leaves of a plant, gas exchange takes place.
• Photosynthesis uses carbon dioxide for plants to produce glucose.
