Diffusion and Osmosis Lab Report By: Jettica Williams BIOL 1107 Lab September 21, 2016 Prepared for Mrs. Fulford Lab Course Page Break The cell membrane act as a roadblock for cells. The cell membrane has a very hectic job. It restricts the access to what comes in and what goes out. The bond the membrane shares with others is the idea of accountability. The cell membrane regulates the deoxyribonucleic acid, enzymes, and it builds a pathways for any reaction such as metabolic. When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport. Active transport is when passage of materials using energy. Passive transport is the passage of materials using kinetic energy. Molecules doesn 't have a preselected motion, and are always on the go. If the molecules was to clash to have a clash or have a run in with the membrane they would recover. If the pore is open the molecules will move towards the open pore and sometimes there 's a possibility that it would recover and go through. The size of the pore matters as well. Diffusion is when the movement of molecules from an area of high concentration to an low area concentration. Osmosis is the movement of water
