Osmosis Egg Lab
Objective:
To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid), syrup (60% sugar solution), and water (100% distilled).
Hypothesis:
Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours.
Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment.
Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours, losing mass.
Introduction:
Osmosis occurs when water from extracellular fluid from the interior of the cell also diffuses freely through the cell membrane, in a way that concentration of water on both sides of the membrane are equal.
Isotonic: When …show more content…
Mainly because it’s controlled by the responsibility of the system to grow. The rate of passive transport relies on the permeability of the cell membrane depending on the arrangement and features of the membrane lipids and proteins. Simple diffusion is the movement from area of higher concentration to areas of lower concentration. This is an example of passive transport. Osmosis and facilitated diffusion are known to be other examples of passive transport. Osmosis occurs when water molecules are diffused and facilitated diffusion is when a molecule can’t pass freely across the cell membrane with requiring one of the two proteins: carrier proteins which are large carriers that use channels, and channel proteins which contain sodium (Na+). Passive transport also occurs for only very small molecules such as oxygen (O2) with equals two atoms, carbon dioxide (CO2) and water (H2O) which both equal three atoms. The size of a cell is determined by how far O2 and CO2 can travel in a cell. Diffusion can only work well over short distances. Diffusion limits cell …show more content…
Endo means within, while cytosis means transport. Endocytosis has three main forms. One form is “Pinocytosis” which is known to ingest liquid into a cell by the development of small vesicles from the cell membrane. “Phagocytosis” is the second form, by which its purpose is to ingest bacteria or other material such as food particles. The third and final form is “Receptor Assisted Endocytosis” that’s known to take certain molecules that are joined to important proteins in the cell membrane that are served as receptors. Taking away waste from the cell this was is called “exocytosis”, which also requires
