• When a particle wants to leave a cell it uses the process of exocytosis
• Exocytosis is possible because the vacuoles fuse with the cell membrane and forms an exit hole]]> 2017-11-02 15:32:21 UTC https://padlet.com/tbuhler23/dabm24029tg2/wish/202963929 Importance of The Cell Membrane tbuhler23 https://padlet.com/tbuhler23/dabm24029tg2/wish/202964038 Every cell is surrounded by a Cell Membrane.
Lipids are a group of organic compounds found in living things.
The Cell Membrane is selectively permeable. This means only some substances can cross the Membrane and some cannot.
The Cell Membrane is the "brain" of the cell.]]> 2017-11-02 15:32:30 UTC https://padlet.com/tbuhler23/dabm24029tg2/wish/202964038 Forms of Passive Transport aordonez23 https://padlet.com/tbuhler23/dabm24029tg2/wish/202964710 Passive Transport is the movement of dissolved materials across the cell membrane without using the cell’s energy. There are two types of passive transport, diffusion and osmosis.
Diffusion is the process of molecules moving from an area of high concentration to one with low concentration. There is also facilitated diffusion what is a form of passive transport that uses channels made of protein in the cell membrane that allows sugars to pass through the cell membrane.
Osmosis is the diffusion of water molecules across the selectively permeable membrane. Many cells depend on osmosis because it circulated the water needed.]]> 2017-11-02 15:33:39 UTC https://padlet.com/tbuhler23/dabm24029tg2/wish/202964710 Active Transport dclearfield23 https://padlet.com/tbuhler23/dabm24029tg2/wish/202966010 Active transport is the movement of materials across a cell membrane using cellular energy. Molecules in cells often move in the opposite direction from their usual way of movement due to diffusion. The molecules move from a place of lower concentration to a place of higher concentration. Substances that are carried into and out of the cells by active protein transportation include calcium, potassium, and sodium. Proteins within the cell membrane play a key role in active transport. Cells have to supply energy to do this specific cell function. ]]> 2017-11-02 15:35:43 UTC https://padlet.com/tbuhler23/dabm24029tg2/wish/202966010
