Tissue

In biology, a tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function.

Types of Tissue

In animals, the main types of tissue are:

  1. Epithelial Tissue: Covers body surfaces, lines hollow organs and cavities, and forms glands.

  2. Connective Tissue: Supports, protects, and binds other tissues. Includes bone, blood, and fat.

  3. Muscle Tissue: Responsible for movement. Includes skeletal, cardiac, and smooth muscle tissues.

  4. Nervous Tissue: Conducts impulses to and from body parts. Composed of neurons and neuroglia.

In plants, the basic types of tissue include:

  1. Meristematic Tissue: Responsible for plant growth.

  2. Permanent Tissue: Differentiated tissue that makes up the plant body, including epidermal, ground, and vascular tissues.
