Solution:On the basis of structure and location tissue systems in plants are divided into three types of tissues.This includes the epidermal tissue system,the ground tissue system and the vascular tissue system.
The Epidermal Tissue System
The outermost covering of the plant body is formed by the epidermal tissue system.
It is formed by epidermal cells,stomata,and the epidermal appendages. The epidermal appendages include the trichomes and hairs.
The outermost layer of a plant is known as the epidermis.It is a single-layered structure.
The outer portion of the epidermis is covered by a waxy layer called the cuticle.and it helps to prevent the loss of water.Cuticle is absent in roots.
Stomata are seen in the epidermis of leaves
The Ground Tissue System
The ground tissue system is formed by all the tissues except the epidermis and vascular bundles
It contains simple tissues like parenchyma,collenchyma, and sclerenchyma
The Vascular Tissue System
The vascular system is formed of complex tissues called phloem and xylem
In dicotyledonous stems,cambium is formed between vascular tissues phloem and xylem
In the monocotyledon stems,cambium is absent between xylem and phloem
The main function of xylem tissue is to conduct tissue for water and minerals from roots to the stem and leaves and it also provides mechanical strength to different plant parts.
The main function of phloem tissue is the transport of food materials mainly from leaves to other parts of the plant
