Define Tissue in biology

Updated on Jan. 8, 2021 03:23 PM IST by Lakshmi Arya

Animals and plants both are multicellular organisms. These are made up of many different types of cells. All cells are not able to perform all the functions. A group of cells that are similar in structure and performing same functions are called as Tissues. Different types of tissues combine together to form an organ, which are capable of performing a specialized function in these organisms. Plants and animals both have different types of specialized tissues and organs to perform specific functions.

Animal Tissues:-

  1.  Most of the part of animal tissues are living.
  2.  They need more energy and Their growth is balanced and controlled (uniform).

Plant Tissues:-

  1. Plants do not show locomotion. So, most of the tissues in plants are to provide support to the plants.
  2. Most of them are made of dead cells, thus the growth in plants is restricted to a few parts only. They need less energy.
  3. Some tissues keep on dividing throughout the life of the plant.

Plant tissues can be grouped into two types:-
1) Meristematic Tissues and 
2) Permanent Tissues
