Question

Which among the following statements are true?

• A. Lenticles perform functions similar to stomata.
• B. Chlorophyll pigment captures sunlight.
• C. Transpiration helps in absorption of water from soil.
• D. Roots are the organ for transpiration.

Answer 1

Answer: (A), (B), (C)

The correct options are
A Lenticles perform functions similar to stomata.
B Chlorophyll pigment captures sunlight.
C Transpiration helps in absorption of water from soil.

• Exchange of gases takes place in leaves through stomata. In stems, lenticels are the site for exchange of gases. These are the tiny openings which protrude from the barks of woody stems. Besides, exchange of gases they also perform transpiration, lenticular transpiration.
• Chlorophyll pigments are present in green plants. They are responsible for trapping of sunlight which is used in photosynthesis.
• Transpiration is the process of loss of excess water in the form of vapour from the plants. Stephen Hales described leaves as the organ of transpiration.
