define parenchyma,collencyma,sclerencyma​

Answer 1

Hey friend,

Here is the answer :-

◼ Parenchyma : These are extremely simple types of permanent tissue whose cells are usually isodiametric. There exists intercellular spaces among the cells and a direct communication interaction takes place through lenticels. If the parenchymatic cells have chloroplasts then the phenomenon of photosynthesis takes place and here parenchyma is called chloro tissue.

◼ Collenchyma : Such tissues are made up of cellular walls and intercellular spaces, there exist an irregular thickenings of cellulose and pectin. Collenchyma tissue is basically a mechanical tissue and its existence always provides a rigid support to the plants.

◼ Sclerenchyma : Sclerenchyma tissues are the components of the hard coating of the several seeds and nuts. Sclerenchyma contains of lignin which makes it hard. The main functions of such tissues are to provide a mechanical support and rigidity to the plant organs.
