Tissue is like a group of cells, which can be the same or different but doing a specific job in the body of a plant or animal.
(i) Meristematic Tissue
(ii) Permanent Tissue
Meristematic tissue consists of cells capable of dividing. These meristems are found in specialized regions of plants and are responsible for their growth.
Types of Merismatic Tissue
Permanent tissues develop from meristematic tissue and consist of cells that no longer have the ability to divide.
Types of Permanent Tissue
As we know, different types of tissues are based on the types of cells they consist of. However, tissues in plants also exhibit variation based on their location within the plant body, which in turn affects their structure and function.
In this document, we will delve into the concept of tissue systems in plants, specifically focusing on the three main types: the epidermal tissue system, the ground or fundamental tissue system, and the vascular or conducting tissue system.
In higher plants, several tissues work together in form of a unit to perform a particular function. These tissues have the same origin. Such tissues form a system which is called tissue system. On the basis of the division of labour, position & morphology tissue is categorized by Sachs (German scientist) into three types of tissue systems. Each system usually consist of an association of tissues which perform specific function.
(a) Structure of Epidermis
(b) Role of Cuticle
(c) Stomata and their Function
(d) Epidermal Hairs
Ground tissue is a type of plant tissue that makes up the bulk of the plant body, excluding the epidermis and vascular bundles. Ground tissue is composed of simple tissues, including parenchyma, collenchyma, and sclerenchyma.
Main function of Ground Tissue System:
Manufacture and storage of food material.
Mechanical support (additional work)
(a) Parenchyma
(b) Collenchyma
(c) Sclerenchyma
The vascular system in plants is composed of complex tissues called phloem and xylem. Phloem and xylem together constitute vascular bundles, which are responsible for the transport of water, minerals, and nutrients throughout the plant.
(a) Vascular Bundles in Dicotyledonous Stems
(b) Vascular Bundles in Monocotyledons
(c) Radial Vascular Bundles
(d) Conjoint Vascular Bundles
