Osmosis Lab Report

Every matter is made of molecules and they are always in motion. However, there are different types of movements and one example is osmosis, which is a type of passive transport, meaning that they do not need energy to move areas of high concentration to areas of low concentration. Osmosis is the diffusion of water across a selectively permeable membrane which means that water can go through membranes from areas where there are a lot of water molecules to areas where there are not so many water molecules. Adding on, cells must continue keeping an internal steady state called homeostasis in order to continue performing their functions. A selectively permeable membrane is used to maintain the homeostasis by controlling the movement of materials into and out of the cell as well as telling different substances apart and slowing down or stopping the movement of some substances while allowing others to pass through freely.

In an hypertonic environment, the net movement of water goes out of the cell and the cell would shrink. Furthermore, the solution will be hypertonic to the cell. On the other hand, in an hypotonic environment, the net movement of water will go into the cell, the cell will expand, and the solution would be hypotonic to the cell. In an isotonic solution, there will be no net movement, the cell would not change in size, and the solution will be isotonic to the cell. Continuing further, hypertonic solution includes more dissolved solute while the hypotonic solution holds less dissolved solute. Lastly, in an isotonic solution, it had the same amount of dissolved
