GENERAL HISTOLOGY

Detailed explanation-1: -Multicellular organisms are organisms that are made up of more than one type of cell and have specialized cells that are grouped together to carry out specialized functions. Most life that you can see without a microscope is multicellular.

Detailed explanation-2: -In multicellular organisms cells differentiate and specialize to form tissues which cooperate to form organs such as brains, kidneys, hearts, stomachs, and lungs. Without specialized cells multicellular organisms would be nothing more than a homogeneous lump of cells.

Detailed explanation-3: -Multicellular organisms consist of “multiple” cells. However, they not only have many cells, but specialized cells that carry out different functions. Groups of cells form tissues and organs, which perform different functions for the survival of the organism.

Detailed explanation-4: -Multicellular organisms delegate biological responsibilities such as barrier function, circulation, digestion, respiration and sexual reproduction to specific organ systems such as the skin, heart, stomach, lungs, and sex organs.

Detailed explanation-5: -An organism which is made up of more than a single cell is called multicellular. The number of cells can be very high. The human body, for instance, comprises about 10, 000 billion cells. An organism which is made up of more than a single cell is called multicellular.
