Multicellular Organisms

Cells are invisible to the naked eye, or in other words, we are not equipped enough to see them. Cells have been previously discussed as the basic building blocks of life and most organisms consist of only one cell and hence are invisible to the naked eye. Others, such as the penguin, the maple tree, and the human being are made of many cells. These are commonly known as multicellular organisms that inhabit our world.

Types of Organisms

This world which we live in consists of a wide variety of living beings. Most of this life is not visible to the naked eye. A microscope becomes necessary to observe these life forms. And the truly tragic part is there is so much left to be beheld, there lie so many organisms yet to be discovered and a lot more that is going extinct. But that is a topic for another day. These tiny organisms are composed of only a single cell and hence aptly named unicellular organisms. The familiar plants, animals, and fungi that we can see represent only a tiny fraction of life on Earth. These organisms are made of more than one cell, are called multicellular.

 Multicellular Organisms

Multicellular organism is an organism composed of many cells, as can be deciphered from its given name. Multi is technically used to refer to something that is more than one, hence multicellular goes to mean more than one cell which are to varying degrees integrated and independent. The development of multicellular organisms is accompanied by cellular specialization and division of labor; cells become efficient in one process and are dependent upon other cells for the necessities of life. So you see, all these multiple cells work together in beautiful coordination to keep an organism alive and in as perfect condition as possible to facilitate their survival.

Hence the main difference between unicellular and multicellular organisms are the unicellular has one cell while the unicellular lays claim to multiple ones.
