Different types of plant tissues on the basis of the capability to divide are:
I. Meristematic tissue
-
Apical meristem brings about primary growth at the shoot and root apex.
-
Lateral meristem responsible for secondary growth of the root and stem.
-
Intercalary meristem responsible for primary growth at the base of leaves and internodes.
II. Permanent tissue
Simple tissue
-
Parenchyma - Stores food and waste products, performs photosynthesis when containing chlorophyll, helps in lateral conduction as a component of phloem and xylem, provides buoyancy and stores gases as aerenchyma.
-
Collenchyma - Provides mechanical strength as well as flexibility to stem, petioles in young dicots, performs photosynthesis when containing chlorophyll.
-
Sclerenchyma - It is the main mechanical tissue of plants and provides strength and rigidity to withstand environmental strains.
Complex tissue
-
Phloem - It helps in the transport of organic food inside the plant body.
-
Xylem - Transport of water in plants occurs in the xylem. It also provides mechanical strength to the plant.
