Question 6
When we observe the lower surface of a leaf through a magnifying lens we see numerous small openings. Which of the following is the term given to such openings?
(a) Stomata
(b) Lamina
(c) Midrib
(d) Veins
The answer is option (a).
Stomata are tiny openings or pores that are used for gaseous exchange. They are mostly found on the under-surface of plant leaves. Air enters the plant through these openings. The carbon dioxide from the air is taken through these tiny pores to carry out the process called photosynthesis.
