Question

Identify the correct type of simple tissue indicated in the options and their function.

• A. Collenchyma- Provides mechanical support to organs.
  
• B. Parenchyma- Photosynthesis, storage and secretion.
  
• C. Sclerenchyma sclereids- Transport food material.
  
• D. Sclerenchyma fibres- Provide mechanical support to the growing parts of the plant such as the young stem and petiole of a leaf.
  

Answer 1

The correct option is B Parenchyma- Photosynthesis, storage and secretion.


Figures given in the options are collenchyma, parenchyma, sclerenchyma fibres and sclerenchyma sclereid, respectively.

• Parenchyma- They are simple living non-mechanical tissue and It is involved in photosynthesis, storage and secretion.
• Collenchyma- They are simple living mechanical tissue and It provides mechanical support to the growing parts of the plant such as the young stem and petiole of a leaf.
• Sclerenchyma- They are 2 types of sclerenchyma tissue (simple non-living mechanical tissue) and they are:

1. Sclerenchyma fibres- It provides mechanical strength to various plant organs and specialised to tolerate stress of bending, shearing, compression and pull.
2. Sclerenchyma sclereid- It forms a protective covering of testa in many legume seeds.
