Detailed explanation-1: -Multicellular organisms possess more than one cell that performs various functions together as a unit. Example: plants, animals. Humans are multicellular. The cells of multicellular organisms have been specialized to perform various functions.

Detailed explanation-2: -As well as humans, plants, animals and some fungi and algae are multicellular. A multicellular organism is always eukaryote and so has cell nuclei. Humans are also multicellular.

Detailed explanation-3: -There are about 100 trillion cells that make up the human body. A new megascience endeavor will catalog and image each of the 200 or more types of cells from the 80 known organs and identify the genes that are active in these cells.

Detailed explanation-4: -Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Detailed explanation-5: -An organism which is made of more than one cell is called a multi-cellular organism. Humans, animals and plants are some multi-cellular organisms which are made of millions to trillions of cells.
