Question

What is a tissue and its function in animals and plants

Answer 1

A group of cells having common origin, similar structure and performing a definite function is called a tissue.  Tissues are found in plants and animals.  Plants and animals are made up of many different kinds of tissues. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. Different types of tissues have distinctive architecture best suited for what they do.  We will see that plant tissues are different from animal tissues in many ways.

Plant Tissues

Plant tissues can be grouped into two basic types: meristematic and permanent tissues.

Animal Tissues

Animal tissues can be grouped into four basic types: epithelial, muscular, connective and nervous tissues.
