Cellular Organisation

Cellular organization refers to the parts that make up a cell as a whole. Each individual organelle in the cell serves a specific function.

Escherichia coli are rod shaped bacteria that are anaerobic. E coli is a bacteria meaning it’s a prokaryote and does not contain membrane bound organelles. For instance e coli would not have a nucleus unlike a mountain gorilla as it’s a membrane bound organelle but it does contain nucleoids.  The mountain gorillas cells are eukaryotic meaning they’re enclosed in a plasma membrane that contains the membrane bound organelles and nucleus. Unlike the cells of plants or fungi mountain gorilla cells do not have a cell wall. The lack of a cell wall in the gorillas cells allow for greater cell diversity and the formation of tissues and organs. On the other hand E. coli has a cell wall made up of two concentric lipid bilayers not cellulose like a plants cell wall would. This cell wall helps to create the rod shape of the cell and also protects the cell. In the gorillas cells it’s the nucleus that contains the chromosomes where as in E. coli the chromosomes are free floating in the nucleoid area.

E coli contain a area of nucleoid, plasma membrane, flagellum, cytoplasm, capsule and pili. The pili are hair like and help it attach to surfaces. The flagellum is an organ that allows the bacteria to move.

Mountain gorilla cells contain a nucleus, plasma membrane, ribosomes, mitochondria, microfilaments and cytoplasm. There are various types of cells present in a mountain gorilla such as blood, skin, muscle and nerve cells.

The cells of a mountain gorilla are about 10x larger than that of a E. coli cell.
