Movement in and out of cells Diffusion: (mixing molecules) Molecules and ions in a liquid or a gas move continuously. The movement is quite random‚ and the particles change direction as they bump into one another. The particles collide more often when they are close together (when they are concentrated) and so they tend to diffuse‚ or spread out‚ until they are spaced evenly throughout the gas or liquid. The random movement of particles is due to their own kinetic energy. When the diffusion

Cell Membrane – The cell membrane protects the inside of the cell from outside containments‚ keeps the cell in contact and maintains its shape. This relates to mall security guards. They’re job is to protect the mall‚ make sure everything is intact and everybody is safe. Without the cell membrane‚ containments could enter‚ the security guards do the same. Without them‚ bad people or things could happen in the mall. Cell Wall – The cell wall provides structural support and protection to the cells

can diffuse across cell membranes while some substances must be transported across the membrane by proteins. The membrane is in control of what enters and leaves the cell. However‚ certain conditions may damage the cell membrane’s structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s membrane‚ acts with the cell membrane of the cell to prevent the betacyanin
