Cells Make Up Every Living Thing

Cells make up every living thing. They are mandatory to life and its functions. The cell allows us to do our functions, while doing its own (Cobb, ed., 2009). Inside cells, there are organelles that carry out functions for the cell to live. They have many different kinds of organelles, such as the golgi body, endoplasmic reticulum, and the nucleus ("Cellular Transport," 2009). They all have different jobs to allow the cell to function, but the cell membrane has a job that that is done in various different ways. Cell membranes are critical to transporting particles for organelles of the cell.
The cell membrane is the exterior layer of the mammalian cell and one of the plant’s outer layers, is a phospholipid bilayer that keeps

It goes from high to low. Passive transport requires no energy to do it. Some particles, such as carbon and water, can pass through with no effort on the cell’s part. There are three types of passive transport, such as facilitated diffusion, diffusion, and osmosis. Diffusion has to do with going with the concentration gradient. Facilitated diffusion is diffusion using a protein to help. Osmosis involves water and a selectively permeable membrane. Water is diffused in and out the membrane (Liu, Amagai, & Chelen, n.d.). Diffusion is the process of molecules moving from an area of high concentration of the kind of molecule to one of a low concentration (Liu, Amagai, & Chelen, n.d.). They are trying to achieve dynamic equilibrium. Dynamic equilibrium is when the concentration outside and inside are equal to one another. An example of diffusion is when someone sprays perfume on in a corner. The perfume will travel to every corner of the room until it is spread evenly across it. Diffusion’s purpose is to have a particle be spread evenly by moving to a high to low concentration (Liu, Amagai, & Chelen, n.d.). Facilitated diffusion is diffusion, but has protein to help larger molecules move through the membrane. While it may seem to use energy due to it using a protein, it actually doesn’t require energy. The large particles are going to a lower concentration than what is on the other side of the cell ("Cellular Transport," 2009). The
