The Cell Essay -- essays research papers

The Cell TheoryThe electric cell theory states that all living matter is do up of cells and some living organisms consist of a atomic number 53 cell. Other cells serve a surplus purpose within advanced organisms like nerve cells. One theory of a cell states that the first wee of life on this earth consisted of a lot of different types of small protocells. Protocells are cell like organism. These organisms were able to reproduce in a genuinely limited environment because they are so simple. After many years some of the protocells came together and shared their DNA with each other. These protocells eventually became the cells we are poring over now.Type of CellsThere are twain types of cells one is the Prokaryote, a Prokaryote is a cell with no nucleus or organelles with tissue layers, the other, a Eukaryotes are cells that chink a nucleus and organelles and are surrounded by a membrane.Cell StructureThin membranes surround cells this is called the cell membranes, they separat e the inside from the out. The cell membrane is just like the other organelles in a cell because it has its own specialized jobs. One of its jobs is to control what enters and exits the cell and to protect the cell. Cell membranes are made up of fats with big protein molecules inside them. Molecules give-up the ghost across cell membranes by two processes diffusion or active transport. Diffusion is the movement from a high gear direct of molecules to a low level of molecules. Molecules can diffuse across membranes through the ph... The Cell Essay -- essays research papersThe Cell TheoryThe cell theory states that all living matter is made up of cells and some living organisms consist of a single cell. Other cells serve a special purpose within advanced organisms like nerve cells. One theory of a cell states that the first form of life on this earth consisted of a lot of different types of small protocells. Protocells are cell like organism. These organisms were ab le to reproduce in a very limited environment because they are so simple. After many years some of the protocells came together and shared their DNA with each other. These protocells eventually became the cells we are studying now.Type of CellsThere are two types of cells one is the Prokaryote, a Prokaryote is a cell with no nucleus or organelles with membranes, the other, a Eukaryotes are cells that contain a nucleus and organelles and are surrounded by a membrane.Cell StructureThin membranes surround cells this is called the cell membranes, they separate the inside from the out.
