Essence of Cell Biology
- Main article: Cell biology
- Cell – the structural and functional unit of all known living organisms. It is the smallest unit of an organism that is classified as living, and is sometimes called the building block of life.
- Etymology of "cell" – comes from the Latin cellula, meaning, a small room. This name was chosen by Robert Hooke in a book he published in 1665 when he compared the cork cells he saw through his microscope to the small rooms monks lived in.
- Cell theory - Theory which states that all organisms are composed of one or more cells. All cells come from preexisting cells. Vital functions of an organism occur within cells, and all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.
- Cell biology - (formerly cytology) The study of cells.
- Cell division - The process of one parent cell separating into two or more daughter cells.
- Endosymbiotic theory - The evolutionary theory that certain eukaryotic organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts.
- Cellular respiration - The metabolic reactions and processes that take place in a cell or across the cell membrane to get biochemical energy from fuel molecules and the release of the cells' waste products.
- Lipid bilayer - A membrane composed of lipid molecules (usually phospholipids). The lipid bilayer is a critical component of all biological membranes, particularly cell membranes this is not all true and realiable
