Plant tissues consist of two main types of tissue.

Meristematic tissue: The calls in this tissue divide very fast and helps in the growth of plants. Cells are round, oval, polygonal, no intercellular spaces. Present at tips of root, shoot, at nodes and at the sides of the stem

Permanent tissue: The cells of meristematic tissue stops dividing, matures and forms permanent tissue.

There are two types of Permanent tissue:

Simple tissue: All cells are same in structure and perform same function. 

Type of simple tissue are parenchyma, collenchyma and sclerenchyma.

Complex tissue: It consists of group of different types of cells to perform same function.

Types of complex tissue are xylem and phloem.

Parenchyma: Present in soft parts of the plant.

Collenchyma: Provides mechanical support to plant present in stalks. Sclerenchyma: They provide strength and flexibility to the plants.

Xylem: Conduct water in plants from root to shoot. Consists of tracheids, vessels, xylem parenchyma and xylem fibres.

Phloem: Conduct food to all parts of plant. Consist of sieve tubes, companion cell, phloem parenchyma and phloem fibres.
