  1. Osmosis vs. Endocytosis and Exocytosis By: Jackson Scully Doctor Osmosis: Controller of all of the transporter proteins

  2. Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of greater concentration of water to an area of lesser concentration of water. • The diffusion of water molecules is a passive transport method because it does not call for the cell to use energy. • If cells are placed in solutions that are very diverse in concentration from that of the cell, the cells may be injured and even wither or rupture (lyse). Osmosis

  3. Another process of active transport happens when molecules are too large to pass through a cell membrane even with the aid of transport proteins. These molecules require the use of vesicles to help them through the membrane. • If the large molecule is passing into the cell, the process is called endocytosis. • If the large molecule is passing out of the cell, the process is called exocytosis. Endocytosis and exocytosis

  4. Entry of water in to the roots from the soil takes place by this process. • Cell to cell diffusion of water is controlled through this process. • Young cells require stiff condition for their growth which is fulfilled by osmosis. • Turgidity of cells is maintained by the process of osmosis Significance of Osmosis

  5. helps give the cell access to the larger particles outside the cell. • helps transport unnecessary large particles out of the cell to make room for different particles. Significance of Endocytosis and Exocytosis

  6. There are many differences between Osmosis and Endocytosis/Exocytosis. One is that Osmosis is a passive transport and Endocytosis/Exocytosis is an active transport. • The way that the materials are transported are different. Osmosis have transport proteins which help to carry the particles through the membrane while Endocytosis/Exocytosis has vesicles that are like boats and they transport the large particles that cant be transported by transport proteins. Differences

  7. Both Osmosis and Endocytosis/Exocytosis are used to transport proteins. Similarities
