What is the role of the cell membrane in moving substances in and out of cell?
The cell membrane is considered to be semipermeable. This means that it will let some substances through (either in or out), but others it won't. The cell membrane is considered to be 3 layers (lipid, protein, lipid) Certain proteins will help substances into the cell, but some they won't let in. Generally, smaller molecules (oxygen, water, CO2, etc.) will pass through easier than larger molecules (glucose, other sugars). Basically, the cell membrane determines what substances are allowed to pass it/out of the cell. ...
Asked in Osmosis
What are the three types of osmosis?
1.] Isotonic - concentrationg is the same on the outside and inside [dynamic equilibrium] 2.] Hypotonic - concentration of substances lower outside the cell, water flows in, turgor pressure increases, and cell bursts 3.] Hypertonic - concentration of substances higher outside the cell, water flows out and cell shrinks ...

Asked in Cell Biology (cytology)
What dos cell membrane do?
It has several functions mainly: 1)Protects the inner part of the cell 2)Separates the cytoplasm from intercellular space (compartmentalization) 3)Allows the passage of ions, substances etc. by diffusion or transport proteins in or out of cell 4)Contains receptors for hormones mainly but other substances also. 5)Contains glycolipids that act as cell markers (they mark the cell in a certain tissue with a certain type for certain functions) ...

Asked in Blood Vessels
What are the blood vessels called that carry blood around the body?
There are three blood vessels. 1. Arteries - these blood vessells carry blood away from heart to the cells of the body. They have a pulse and they are walled with elastic fibres. 2. Veins - Carry blood from the other parts of the body to the heart. They have valves to stop backward flow of blood. 3. Cappilaries are only one cell thick in reality, and they help to diffuse substances from the blood to the cell through the cell...
