Question

What is the utility of tissues in multicellular organisms?

Answer 1

Initially Multicellular organisms are made up of one or more cells or complex organs. It has distinct organs and organ systems. Eukaryotic species contain membrane bound structure. Humans, birds, insects and plants have multicellular organs. The function of a multicellular organ is to survive. For surviving cells to work together, In animals skin is used to protect and nerve cells carry signals and muscle cells produce movement. Tissues are the collection of similar cells grouped together to do one function.

Complete answer:
Non living material called intercellular matrix is used to fill the spaces between the cells. There are four types of tissue in the human body. They are epithelial, connective, muscle, and nervous. Every tissue is used for different functions. Primary tissue used in overall health maintenance. Epithelial cells are controlling the movement across the surface by covering the body. Connective tissue is used to protect and support the internal organs. Muscle system used for the movement of the body. Nervous cells are propagating the information. Connective tissue fibers are the strongest tissue. In multicellular organisms tissues are providing the mechanical and structural strength and also enable the division of labor. All the tissues perform different functions in multicellular organisms. So it is called the division of labor. Transmission of messages from the skin to the brain is caused by the nervous tissue. To perform specialized functions special tissues are available in the multicellular organism. Connective tissue used to connect the bone; blood and blood lymph works together to perform special functions. Epithelial cells provide various lining passages inside the body. Muscles have three types. They are skeletal, smooth and cardiac.

Note:
Strongest muscle in the human body is in the jaw. Stapedius muscle is the weakest muscle in the human body because it is a small skeleton. Mineralized tissues are called the biological tissue. It incorporates minerals into soft matrices. They are found in animals, plants and algae. It gives the protective shield against predation. Epithelial cells also perform the secretion, excretion and absorption. It helps the human body from injuries, microorganism and fluid loss.
