Meaning of Pluricellular
What is Pluricellular:
The term multicellular is used to describe organisms that are made up of two or more cells. The word is equivalent to multicellular.
Among multicellular organisms we can mention animals, plants and brown algae. The single-celled organisms are amoebae and bacteria.
All pluri or multicellular beings are formed from a single cell, which divides and multiplies to generate an organism. These processes of cellular development are often referred to as mitosis and meiosis.
Cells must, in turn, communicate with each other, which implies that they identify and come together to give unity and function to the organism. This is accomplished through the organization of cells into colonies, filaments, or aggregation.
Each group of cells is specialized according to the function it performs. This difference does not depend only on the type of organism (animal, vegetable or plant) but on the specific function it fulfills within it.
In certain organisms, cells cannot live independently. They require each other to be able to transmit the information and stay alive.
In this class of organisms, cells of the same type, having the same embryonic origin and carrying out the same function, form tissues. Among them we can mention: epithelial tissue, cartilage tissue, bone tissue, muscle tissue, connective tissue, nervous tissue and, finally, blood.
Multicellular tissues make up organs. The set of organs make up systems, such as the cardiovascular system or the digestive system. Ultimately, systems make up the organism.
