Anatomy Of Flowering Plants Question 80

Question: Identify the types of simple tissue indicated by 1, 2, 3 and 4 and their function.

Options:

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.

Show Answer

Answer:

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.
