Question

What is plant tissues ? ​

Answer 1

Answer:

Plant tissue - plant tissue is a collection of similar cells performing an organized function for the plant. Each plant tissue is specialized for a unique purpose,and can be combined with other tissues to create organs such as flowers,leaves,stems and roots.

Answer 2

Answer:

===>plant tissue is a collection of similar cells performing and organised function for the planet.

===>Each plant tissue is specialised for a unique purpose, and can be combined with other tissues to create organs such as flowers, stems, roots and leaves.

Explanation:

function of plant tissue:-

===> Help provide mechanical strength to plants.

===>They help providing elasticity and flexibility flexibility to the organs.

Types of plant tissue:-

===>Merismetic tissue .

===>Permanent tissue

Merismetic tissue :-

===>Group of cells that have ability to divide.

===>Merismetic tissue give rise to permanent tissue.

===>Merismetic tissue are living things.

Permanent tissue:-

===>permanent tissue are made of meristematic cells.

===>The tissues that are completely grown and have lost the ability of division are known as permanent tissue.

Types of permanent tissue:-

===>simple permanent tissue.

===>complex permanent tissue.

simple permanent tissue:-

===>Simple permanent tissue also known as homogeneous tissues, there are made up of single cell type, usually with the same origin, structure and function.

[simple permanent tissue is further classified into three types]

===>Parenchyma:-

===>The cells have an oval or round shape.

===>The cell wall is made up of hemicellulose or cellulose.

===>The cell is thin walled.

===>Collenchyma:-

===>Cells are long and thick walled.

===>cell wall is made up of cellulose and

pectin.

===>it is the only tissue with the highest refractive index due to the presence of pectin.

===>sclerenchyma:-

===>These are dead tissues very hard and rigid in textures.

===>cells are thick walled with various size and shape.

===>it's provide mechanical support and rigidity to the plants.

complex permanent tissue:-

===>complex permanent tissue is made up of various types of cell carrying out distinct functions and are of two types:

$\fbox{xylem}$

==>it transports water and nutrients from the roots to leaves of the plants.

==>it provides support to the plants.

$\fbox{phloem}$

==>Phloem also called bast.

==>Phleom is composed of various specialised cells is called sieve tubes, companion cells, fibres, and phleom parenchyma cells.
