BOTANY

Detailed explanation-1: -The prefix “multi” means many and cellular means about or involving cells. So, a multicellular organism definition is: an organism that is made of many cells, such as plants, animals or fungi. Multicellular organisms are different from unicellular organisms, such as bacteria, which are only made of one cell.

Detailed explanation-2: -The kingdom Plantae includes organisms that range in size from tiny mosses to giant trees. Despite this enormous variation, all plants are multicellular and eukaryotic (i.e., each cell possesses a membrane-bound nucleus that contains the chromosomes).

Detailed explanation-3: -Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.

Detailed explanation-4: -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.

Detailed explanation-5: -Multicellular organisms are made of more than one cell and are complex organisms. They are visible to the naked eye. They possess distinct organs and organ systems. They are eukaryotes, i.e., they contain membrane-bound structures.
