Tissue:

A group of cells that are specialized to perform a particular function forms a tissue.

Tissues are mainly classified into two types:
1. Plant Tissues
2. Animal Tissues

  • Cells form groups cells that need to perform a single task often group together.
  • This grouping of cells together to perform a function efficiently is called a Tissue.
  • For Example, Muscles and Blood.
  • The tissue cells have the same structure and they perform the same function.

Tissues of Plants and Animals:

Plant Tissues

Animal Tissues

plants do not move so their tissues are predominantly the ones that provide support to them so that they can stand erect.

Animals need more energy as compared to plants because they are not stationary. Their tissues are the ones that can support movement.

These tissues are made up of dead cells because dead cells can also provide mechanical strength to the plants and do not require much maintenance.

The tissues in case of animals are made up of living cells so that they can move and perform several functions.

Only certain parts of the plant can grow. The tissues present in such regions of and divide themselves and form new tissues.

Cells in animals grow uniform early and not only in certain regions of the body.

The structure of plant tissues is not very specialized as compared to animals

The organs and organ systems in animals are highly developed.
