Question

A group of tissues performing a particular function in the body forms a/an
(a) Cell
(b) Tissue
(c) Organ
(d) Organ system

Answer 1

Hint: Tissues are a group of similar cells that have a common function which further associate to form a more complex structure.

Complete answer:
The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.

Additional information:
1. Cells are the basic unit of life. A group of cells having the same structure and performing the same function forms a tissue.
2. All tissues consist of cells and extracellular materials.
3. Cells of the specific categories have similar functions, although some cells of nervous tissues and epithelium overlap.
4. Organs are of two types: parenchyma (tissue which forms various organs) and stroma (tissues having various functions including support, connection, and structure)
5. A group of organs that work together to maintain a stable internal environment and perform a particular function is called an organ system.
6. In humans and other multicellular animals, cells are made up of four basic tissue types – epithelial cells, connective tissue, muscle tissue, and nervous tissue.
7. The whole body constitutes muscles whereas the heart also is made up of specialized muscle cells. The outer layer of the skin is called epithelial tissue.
So, the correct answer is ‘Organ’.

Note: The English word “organ “ dates back to the twelfth century about any musical instrument. At the same time, a second meaning arose, about a “body part adapted to a certain function “. Human anatomy was first studied and discovered by Andreas Vesalius, he studied various organs of the human body. Recently, a new organ called mysentry was discovered by scientists which results in a total of 79 body organs.
