• A. Sclerenchyma
• B. Collenchyma
• C. Phloem
• D. None of the above
  

Answer 1

The correct option is A Sclerenchyma

A. Sclerenchyma is known as the supporting tissue of the plants which make the plant hard and stiff as their cell wall is made up of cellulose, hemicellulose and lignin.

B. Collenchyma consists of cells with irregular and thickened cell walls which provide structural support to the plants.

C. Phloem tissues help to conduct food made in the leaves to all other parts of the plant and it consists of sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.

So, the correct answer is 'Sclerenchyma'.
