I know from reading title you’re probably wondering what this is all about. This blog is exactly what the title says it is.. it’s about comparisons. I’ve always been a lover of science and I’ve always been fascinated by how different organisms work.The aim of this blog is not only to inform and educate but it’s also to help you to have an appreciation for differences. In society we often try to hide our own uniqueness and diverse individuality in hopes of trying to blend in with the crowd and trying to gain some form of acceptance. However in the world of nature it is these very same differences that defines, supports and maintains species.
I’ll be comparing a multicellular organisms against a unicellular one. Before we go any further we need to understand the differences between ‘multicellular’ organism and a unicellular one.
By definition a multicellular is an organism composed of many cells which are to varying degrees integrated and independent. Is simpler terms a tissue, organ or organism that is made up of many cells is said to be multicellular . Animals, plants and fungi are multicellular organisms and often there is specialisation of different cells for various functions.
Fun fact: Multicellular organisms haven’t always existed, the first multicellular fossils have been found in a 2.1 billion years old Palaeoprterozoic rock from Gabon Africa.
In contrast Unicellular or single called organisms are much smaller in size and less complex as they are compasses of just one cell that senses it’s environment, gathers nutrients and reproduces asexually. This implies that in one cell, all life processes occur, such as reproduction feeding, digestion, and excretion. Amoebas, bacteria, and plankton are only several examples of species that are unicellular. Usually they are microscopic meaning that cannot be seen by the naked eye.
Fun Fact : Many unicellular organisms live in extreme environments, such as hot springs, thermal ocean vents, polar ice, and frozen tundra.
In this blog I will be comparing Paramecium Caudatum which is a unicellular organism with Fungi which is a us human beings because we are in fact multicellular organisms.
