Also I will be taking a look at the endosymbiotic theory - specifically looking at mitochondria and chloroplasts. Firstly I would like to show some of the common features between eukaryotes and prokaryotes. They are: 1. DNA - the genetic material within one or more chromosomes. In Eukaryotic cells, DNA is located in a membrane-bound nucleous, and in a prokaryotic cell, it is located in a non-membrane bound nucleoid region. 2. Plasma Membrane - protects their contents and act as a barrier to the environment. Small molecules like Oxygen, Carbon Dioxide and water can pass through the membrane, but larger molecules such as amino acids and sugars are carefully filtered. 3. Cytoplasm - the watery fluid that makes up the rest of the cell. It can be defined as anything between the membrane and nucleus. 4....
