Answers
Answer:
The two columns are matched and written as follows:
(a) Pitcher - Trapping insects
(b) Spines - Protection
(c) Phyllode- Photosynthesis
(d) Tendril- Climbing
Pitchers are insectivorous plants that have modified leaves in order to trap insects.
Spines are modified leaves, stems and other parts of the plant which protect it from animals.
Phyllodes are modified leaf stems that perform photosynthesis.
Tendrils are specialized structures of plants that is utilized by plants for climbing along a support.
Answer:
(a) Pitcher - (iii) Trapping insects
(b) Spines - (iv) Protection
(c) Phyllode - (i) Photosynthesis
(d) Tendril - (ii) Climbing
Explanation:
A)
Pitcher plant is a carnivorous plant with modified leaves. It lures the insects and traps them into the deep cavity and digests them. Therefore, it is (iii) trapping insects.
B)
Spines/thorns are hard stems with sharp ends which protects them from to be eaten from other animals. They also help in less loss of moisture from them. Therefore, spines are helping in (iv) protection.
C)

Phyllode are flatter and bigger version of petiole. They are found in acacia trees and shrubs. They help in surviving in difficult environments. Therefore, phyllode helps in (i) photosynthesis.
D)
Tendril : They are thread like structures which help in climbing in plants. It is spiral in nature. tendrils are modified leaf, leaflets or stipules. Ex: grapes. Therefore, tendrils helps in (ii) Climbing .
