Question

What is the difference between collenchyma and sclerenchyma

Answer 1

Collenchyma cells consists of thin primary walls and provide extra structural support in regions of new growth. Collenchyma cells have walls which during their development and extension are mainly cellulosic.


Sclerenchyma is the tissue responsible for providing support to plants. Their cell walls comprises of cellulose, hemicellulose and lignin. Their tissues are of two types - fibres and sclereids.

Answer 2

"Both collenchyma and sclerenchyma are types of plant tissue which are different from each other in many aspects.

Collenchyma:

1. These cells have thin "primary walls".
2. It also has secondary thickening in some of the parts of the plant.
3. It provides extra "mechanical and structural" support to the newly growing parts of plants.
4. They also contain vacuolated protoplasts and do not found in monocots.

Sclerenchyma:

1. These cells have "thick lignified secondary" walls.
2. Sclerenchyma cells often die when they are matured. "
