Question

Very short answer type.
Define a tissue.

Answer 1

The use of tissues in multicellular organisms is to give structural and mechanical power in addition to permit separation of labour. They also are referred to as clusters of cells.

Complete answer:
To answer this question, we have to know about the tissues. Tissue, in physiology, a range of organisation in multicellular organisms; it includes a collection of structurally and functionally comparable cells and their intercellular material. Tissues are absent from unicellular organisms. Even some of the most effective multicellular species, together with sponges, tissues are missing or are poorly differentiated. But multicellular animals and plants which are extra developed have specialised tissues which can arrange and alter an organism’s reaction to its environment.
Plants are less complicated organisms than animals, having 3 organ structures and fewer organs than do vertebrate animals. Organs are composed of tissues, which might become composed of cells. Plants have 3 tissue types: ground, dermal, and vascular. Animals have 4: epithelial, connective, muscle, and bone.

Epithelial tissue- Epithelial tissue is the most cellular tissue which overlaps body surfaces, borders cavities, and develops glands.

Connective tissue- Connective tissue is very abundant tissue kind present in the body. It contains cells which are developed from mesenchyme and an extracellular matrix.

Muscle tissue- Muscle tissue is both extendable and stretchy.

Nervous tissue- The nervous tissue’s cells are extremely specific to transfer electrical impulses all over the body.

Note: Human body tissue is some other manner of describing how our cells are grouped collectively in advance manner based on particular shape and function. These groupings of cells shape tissues, which then make up organs and numerous components of the body. For example, it is easier to look and sense muscle within the body. Muscle is one of the fourth kinds of human body tissue.
