Column-I (Structure) | Column-II (Function) | ||
A | Stomata | p | Protection of stem |
B | Bark | q | Plant movements |
C | Cambium | r | Secondary growth |
D | Hydathode | s | Transpiration |
t | Guttation |
A) A = t, B = r, C = p, D = s
B) A = p, B = s, C = t, D = r,
C) A = q, B = s, C = p, D = r
D) A = s, B = p, C = r, D = t
Correct Answer: D
Solution :
The stomata helps in transpiration, bark protects stem from chemical, mechanical and biological injury, cambium is responsible for secondary growth and hydathodes for guttation.You need to login to perform this action.
