Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant.

Likewise the humans, who have bones to support their body structure, plants also have certain specialized tissues which help them, by providing support to their structure, protecting the inner parts, giving strength, etc. These three tissues (Parenchyma, Collenchyma, and Sclerenchyma) are considered as the ground tissues of the plants and are known to provide mechanical strength to the plant right from its growing stage to lifelong.

Apart from the above-mentioned points, plant tissues also help in the division of the new cells, and in growing of the new plants. It also helps in various metabolic activities. They also help the tissues of the leaf, stems, and branches in bending and protect from the damage.

Tissues are formed from the group of cells performing a specialized function. Plant are also multicellular organisms, containing numerous cells and each one is assigned for the specific activity. Generally, there are two types of plant tissues, these are Meristematic and Permanent tissues. The permanent tissues are again divided into simple permanent tissue and complex permanent tissues.

In this article, we will be focussing about the three types of simple permanent tissues, which are parenchyma, collenchyma, and sclerenchyma tissues. We will also discuss the ground point on which they differentiate.

Answer 2

The difference between the three simple tissues are

Parenchyma  

• It consists of thin-walled living cells.
• They are involved in food storage.
• Comprises of thin cell wall and made up of cellulose.

Collenchyma

• It consists of thin-walled living cells.
• They are the chief mechanical tissue in young plants, particularly dicot stems.
• Comprises of uneven cell wall and is made up of pectin and hemicellulose.

Sclerenchyma

• It consists of dead cells.
• It is mainly a mechanical tissue.
• Comprises of hard and thick cell wall and is made up of the lignin.
