A) 1 - Parenchyma; Photosynthesis, Storage and Secretion.
B) 2 - Sclerenchyma, Sclereid; Transport food material.
C) 3 - Collenchyma; Provides mechanical support to organs.
D) 4 - Sclerenchyma Fibres; Provide mechanical support to the growing parts of the plant such as young stem and petiole of a leaf.
Correct Answer: A
Solution :
[a] Figure 1, 2, 3 and 4 are respectively parenchyma, collenchyma, sclerenchyma fibres and sclerenchyma sclereid. Parenchyma: It is involved in photosynthesis, storage and secretion. Collenchyma: It provides mechanical support to the growing parts of the plant such as young stem and petiole of a leaf. Sclerenchyma fibres: It provides mechanical strength to various plant organs and is specialised to tolerate stress of bending, sheering, compression and pull. Sclerenchyma sclereid: It fans protective covering of test in many linguine seeds.
