Question

What are the disadvantages of multicellularity?

Answer 1

Hint:In biology, one or more cells may be usually made of the organisms. One-cell species are considered unicellular, whereas more complex organisms are multicellular, such as plants and animals. Multicellularity has benefits as well as drawbacks.

Complete answer
To answer this question we have to know about the multicellular organisms. A multicellular organism requires more food than a single-cellular organism, since multiple cells want more energy to eat. The amount of energy available varies from cell type to type of cell.

Infection is a real concern for multicellular organisms from single cellular organisms. Basically, the more complicated and important an organism's cells are the more likely it is that parasites, viruses and bacteria that can contribute to their destruction will attack them.

It takes longer for a multicellular organism to attain adulthood. Not only does maturity take longer to occur, but due to a more complicated genetic makeup, the growth of 'babies' from complex species takes longer.

A multicellular organism consisting of complex cell structures, such as human beings. Multicellular groupings are all made up of the heart, brain, lungs, skin, bones, etc. So if one organ dies, the entire organism will collapse, such as the heart, which can lead to the death of all the cells in the body. Regeneration ability is much lower in multicellular cells due to specificity.

Note:It is easier to do being unicellular, since unicellular life evolved earlier. It often takes less time to feed or grow, as the whole body does. Infection becomes difficult because you are a single-celled organism, since being a single-celled organism means that infection is caused by nothing smaller.
