Question

Group plant tissues on the basis of their characters and function.

Accepted Answer

Tissues are a group of cells that have similar structure and perform a specific function.

Plant tissues can be divided into two types (i) meristematic tissues and (ii) permanent tissues.

Meristematic tissues are those which have the ability to divide rapidly hence are present on the tips, radial stems and internodes.

Old meristematic tissues that have lost the ability to divide are converted into permanent tissues.

Permanent tissues are those that have lost the ability to divide but they offer elasticity, flexibility and strength to the plant.

These are further divided into simple permanent tissues and complex permanent tissues based on the type of cells that they are made up of.

Simple permanent tissues have only one type of cells. They are further classified into (i) parenchyma, (ii) collenchyma and (iii) sclerenchyma.

There is one more type of simple tissue known as dermal tissue which are mainly protective in function and form the lining of all plant parts.

Complex permanent tissues are those tissues which are made up of different types of cells. They are also called as vascular tissues. They are classified into two types: xylem and phloem.

Xylem helps in the conducting water and mineral salts that are dissolved in water. These are constituted of four different types of cells i.e. xylem tracheids, vessels, fibres and xylem parenchyma.

Phloem helps in translocation of food throughout the plant. It consists of phloem fibres, phloem parenchyma, sieve tubes and companion cells.
