The cell membrane doesn’t allow everything to go through it. Biology Dictionary explains that the basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances that go in and out of cells and organelles. Another name for the cell membrane is called selectively permeable membrane because of the main reason being it’s selective nature. The cell membrane will only allow the selected and necessary molecules such as water to pass through it states Socratic Biology. Both osmosis and cells play important roles in any biological life. In animals and humans, osmosis helps transport nutrients and release metabolic waste products whilst in plants osmosis aids the absorption of water from the soil and helps transport it all right up to the leaves of the plant. Sugar is a bigger molecule compared to water therefore it is most likely it won’t pass through the cell membrane alone. There are special proteins that’s embedded in the cell membrane that are specifically required to transport sugar throughout the cell …show more content…
The drinks that contain artificial colouring or basically are a different colour will have an enormous effect on the colour of the eggs within a day or two. This is because of diffusion and osmosis. The colouring in the drink will diffuse throughout the water. If the substance is able to move through the membrane, it will because it is trying to obtain the same density on either side of the membrane, resulting in the colouring of the egg. Center For Nanoscale Science, MRSEC, states that the substances will move from an area of higher concentration (or density) to an area of lower concentration through the membrane. Once the concentration is equal on both sides of the membrane, it is said that the substance has achieved
