Differences between Prokaryotic and Eukaryotic cells A ll living organisms can be sorted into one of two groups depending on the fundamental structure of their cells: The prokaryotes  The eukaryotes.                           P rokaryote s are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles.                               E ukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds genetic material as well as membrane-bound organelles. Definition of eukaryotes and prokaryotes Prokaryotes (pro-KAR-ee-ot-es) (from Old Greek pro- before + karyon nut or kernel, referring to the cell nucleus, + suffix -otos , pl. -otes ; also...

Difference between Antigen and Antibody Topic Antigen Antibody Other names Immunogens Immunoglobulins Definition A substance that trigger an immune response A type of protein that binds to antigen Origin Can be found on external source or within the body Within the body Molecular type Proteins, lipids, polysaccharides, and nucleic acid. Proteins Binding site Epitope Paratope Effects on the body It is responsible for causing a disease or an allergic reaction. It protects the body from harmful microorganisms. Significance/importance It controls what goes in and out of the cell. It protects the body from infection, especially in the case of a virus attack. Prevalence Found in almost all types of cells (bacteria, viruses, and fungi) Present in some type of cells. ( 11 ) Location/Where can they be found? Antigens are hook on the cell’s surface and are present in every cell. Antibodies are found in various parts of the body including the following: IgA – It is fo...
