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 water and minerals.
C) 3 - Collenchyma; Provides mechanical support to plant organs.
D) Sclerenchyma Fibres; Provide mechanical support to the non-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 forms protective covering of testa in many legume seeds.
