The similarities and differences between eukaryotic and prokaryotic cells Prokaryotic and Eukaryotic cells are the two main types of cell found in living organisms. They share many similarities and also many differences. These differences are key to how they function and which jobs they are suitable to perform. Prokaryotic cells are cells that contain a very primitive nucleus as pro- means before and karyon ... nucleus present. As there is no nucleus present in prokaryotic cells the DNA helix is a single coiled chromosome that is unsupported and so can float freely around the cell, however in...

How the Molecular Structure of Carbohydrates, Proteins and Lipids affect their function in living things. Living cells contain many small molecules such as water and inorganic ions like nitrogen. They also contain a vast number of larger molecules, called macromolecules that are built ... immediate supply of glucose is used up the body restores its supplies by breaking down glycogen. Cellulose is an example of a structural polysaccharide, and it gives strength and rigidity to plant cell walls. Cellulose molecules are long unbranched chains of containing glycosidic linkages of B-glucose. The ...
