What is tissue with example?

A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

What is the importance of tissues Class 9?

It covers most organs and cavities within the body. It also forms a barrier to keep different body system separate. Epithelial tissues help in absorption of water and nutrients.

What is the main function of epidermis Class 9?

The function of epidermis is the protection of plant from injury and infection. Cuticle of epidermis also helps to reduce water loss by evaporation to prevent dessication. Stomata present in the epidermis allow gaseous exchange to occur during photosynthesis and respiration. It also facilitates transpiration.

What is the main function of xylem tissue?

Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

What are the two types of protective tissue?

There are two kinds of protective tissues: the epidermis and the suber or cork.

What is the example of protective tissue?


Why are they called protective tissue?

epidermis and cork cells are known as protected tissue because epidermis and cork cells protect the plant from water loss and protects the plant from insects. epidermis and cork cells had waxy coating known as cutin and suberin which helps the plant from water loss .

What are the three types of permanent tissue?

Simple permanent tissues are again classified into three main types. They are parenchyma, collenchyma, and sclerenchyma.

How many types of simple tissue are there?

three types

What is simple tissue and its types?

Simple tissues are tissues composed of cells that are structurally and functionally similar i.e. they are made up of only one type of cell. Types of simple tissues in plants: i. Parenchyma.

What is the example of simple tissue?

The cells of simple tissue perform similar function. The cells of complex tissue may perform different functions. Example of simple tissues are collenchymas, parenchyma. Examples of complex tissues are xylem and phloem.

What is the type of simple tissue?


Type of tissue Simple/complex Cell types present
Parenchyma Simple tissue Parenchyma
Collenchyma Simple tissue Collenchyma
Sclerenchyma Simple tissue Fibers Sclereid
Xylem Complex tissue Tracheary elements, parenchyma, Sclerenchyma (fibers)

What is difference between simple and complex tissue?

IF the tissues are composed of cells which are functionally and structurally similar, then they are called SIMPLE TISSUES….Difference Between Simple And Complex Tissue.

Simple Tissues Complex Tissues
Nature of the Tissue
Homogenous Heterogenous
Parenchyma, Collenchyma, Sclerenchyma Xylem, phloem

What are the types of simple tissues Class 9?

The types of simple tissues are parenchyma, collenchyma, sclerenchyma and aerenchyma.
