    Diffusion And Osmosis Introduction: There are several valuable aspects of this lab that must be understood before it is conducted. The first of these concepts is called diffusion. Molecules are constantly moving and as they are moving they tend to move from areas of higher concentration to areas of lower concentration. Diffusion can be defined as the net movement of molecules from higher to lower concentrations. One example, of diffusion is when an item like perfume is opened in a room.

    There are two types of cell transport mechanisms. These types of transports are passive and active transport. The difference between active and passive is that passive does not require energy and active does require energy. The reason passive does not require energy is because it travels down a concentration gradient. On a concentration gradient molecules naturally move from high to low concentration. In active transport, molecules move from low to high concentration. There are three different types

    Temperature has a great effect on osmosis. Based on our data, the bags that contained water at 55 degrees Celsius had a much greater rate of osmosis than the bags at 15 degrees Celsius. When the environment is heated up, reactions occur at a much faster rate. This is because the extra heat provides more energy. Increasing the concentration also increases the rate of osmosis. This is because there is a lesser concentration of water inside the bag in the 40% rather than the 15%. The water will rush

Osmosis is a type of diffusion.
