Tissues

What You will learn

• Tissue is a group of cells similar in structure and function.

• Plant tissues are of two main types – meristematic and permanent.

• Meristematic tissue is the dividing tissue present in the growing regions of the plant.

• Permanent tissues are derived from meristematic tissue once they lose the ability to divide. They are classified as simple and complex tissues.

• Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Xylem and phloem are types of complex tissues.

• Animal tissues can be epithelial, connective, muscular and nervous tissue.

• Depending on shape and function, epithelial tissue is classified as squamous, cuboidal, columnar, ciliated and glandular.

• The different types of connective tissues in our body includes areolar tissue, adipose tissue, bone, tendon, ligament, cartilage and blood.

• Striated, unstriated and cardiac are three types of muscle tissues.

• Nervous tissue is made of neurons that receive and conduct impulses.
