Question

In a multicellular organism , all cells have the capability to perform all life functions. Do you agree ? Give reasons.

Answer 1

Hint: A multicellular organism is an organism which is composed of many cells. They are developed by cellular specialization and division of labor.

Complete answer:
Multi cellular organisms are organisms that include more than one cell which opposes unicellular organisms. All the species of animals , plants, and most of the fungi are multicellular organisms . Multicellular organisms originate by different methods. That is by cell division or by aggregation of many single cells. Multi cellular organisms pass on biological responsibilities such as barrier function, circulation, digestion, respiration and sexual reproduction to explicit organ systems such as the skin, heart, stomach, lungs, and sex organs. These organs consist of many different cells and cell types that work jointly to perform specific tasks. Animals, plants, and fungi are multicellular organisms and frequently, there is specialization of different cells for various functions.

Organisms made up of more than one cell are categorized as multicellular organisms. On the other hand, multicellular organisms haven’t always existed. Following the formation of the Earth, it took about one billion years for a unicellular organism to come into view on the planet.In detail,Unicellular organisms existed alone on the Earth for approximately two billion years before the manifestation of multicellular organisms, which occurred just about 600 million years ago.

In a multicellular organism all the cells do not have the ability to perform all the bodily functions. Different cells in multicellular organisms have different functions to perform. For example WBCs are involved in providing protection whereas hemoglobin which is a protein present in the red blood cells carries the oxygen. Red blood cells also help to remove carbon dioxide from the body and transport to the lungs for exhalation.

So we can conclude that all the cells in a multicellular organism do not have the capability to perform all the life functions.

Note:All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium.
