In organisms that follow sexual reproduction, gametes combine to form the zygote, the first cell of a new organism. We will discuss the familiar case of humans, but the same applies to other organisms as well. The two gametes, sperm and egg, are haploid cells, meaning they contain half the chromosome number of somatic cells. […]

What are the differences between unicellular and multicellular organisms when it comes to their functions? We already know that three of the basic functions of living organisms are survival, growth, and reproduction. In order to survive and grow, a cell needs nutrients and oxygen. Moreover, it needs to get rid of carbon dioxide and waste […]
