PLANT TISSUES

PLANT TISSUES

In plants meristematic tissues are classified into three types of permanent tissue.

• Simple permanent tissue• Complex permanent tissue• Special or Secretary tissue Common types of simple permanent tissues are parenchyma,

Collenchyma, Sclerenchyma. Complex tissue is also known as vascular tissue. Common types of

complex tissue are Xylem and Pholem.

Parenchyma

Composed of cells with the simplest structure

Seen in the soft parts of the plant

Helps in photosynthesis and the storage of food

Collenchyma

Composed of cells that are thick only at the corners of the cell wall

Provides flexibility and support to plant parts

Sclerenchyma

Composed of cells that are uniformed thick all over the wall

Provides strength and support to plant parts

Xylem

Transports water and minerals absorbed by the roots to the leaves . Has thick cell walls and therefore provide support and strength to the plant.

Tubes formed from elongated cells

Phloem

Transports food synthesized in the leaves to various parts of the plant body.

Composed of tubular inter –connected cells.
