Tonicity

is less concentrated in comparison with your body, thus, it is using osmosis to get into our body. Putting rice in water and boiling is pretty much the same, the water will move into the rice, causing it become cooked or swell. Relating to this, tonicity is the ability to of an extracellular solution to make water move either inside…

The egg is an example of an animal cell that is placed in environments of different tonicity. The vinegar was used to dissolve the shell so that we can see the effects when we placed the egg either in a hypertonic or hypotonic solution. Since the egg membrane is semipermeable similar to the cell membrane, it only allows specific substances to pass in and out of the egg membrane down its concentration gradient. In this case, we are trying to measure to the diffusion of water that goes in and out…

Movement of materials from areas of high concentration to areas of low concentration id diffusion. Osmosis is diffusion of water. Tonicity compares the environment inside of a membrane with the outside. When a membrane bound structure has a higher concentration of water on the outside of the membrane than the inside is hypotonic. Hypertonic is when a membrane bound structure has a higher concentration of water on the inside of the membrane than the outside. When something is isotonic the inside…

Necrosis occurs as a result of external injury due to cellular injury, bacterial toxin or trauma to a particular area of the body. Necrosis differs from apoptosis in a couple of ways. First, the morphological changes that a cell undergoes are different in necrosis compared to apoptosis. Secondly, apoptosis is highly regulated, however, necrosis is unregulated. The morphological changes that a cell undergoes during necrosis are the swelling of the cytoplasm, irreversible damage to the plasma…

Animal cell membranes are selectively permeable and allow certain substances in and out through passive or active transport. While plant cells have a cell wall to combat high concentrations of water, animal cells only have a cell membrane. This lack of support can make a hypotonic animal cell expand and burst. A hypertonic animal cell will undergo osmosis and release water eventually causing the cell to shrivel up and shrink. Both of these results make it extremely important for animal cells to…

Various industrial essential metabolites ,such as organic acids,antibiotics and enzyme, are produced by filamentous fungi .The morphology of these micro-organism in submereged culture varies between the pelleted and the unrestricted filamentous form, depending on the strain and the culture conditions (Braun et al., 1991).The fungal morphology for these fermentation is of great importance since it affects the rheaological properties of the fermentation broth and consequently its mass, heat and…

INVESTING DIFFUSION THROUGH LIVING MEMBRANES Introduction Cells are living membranes. They are the basic unit of life. They are very unique in that they have the capability of carrying out a large number of chemical reactions in the body, ability to respond to stimuli, capable of producing more of themselves, they have a genetic program and the means to use it, they acquire energy and utilize it, all in the process of the functioning of the human body, The life of a cell is also dependent on…

and to further our understanding we even conducted an experiment with an artificial cell. To start the lesson, we learned the difference between diffusion and osmosis, how concentration gradients affect both. Also how the cell membrane works, how tonicity affects plant and animal cells differently, how dialysis tubing works, and how it acts like a living cell. By the end of the lesson we understood that osmosis is a phenomenon that all cells have to deal with (Thorpe, 2015). To better understand…

The system is what makes up our body, it's the foremost sophisticated of the various systems within the body, and it's conjointly a network of nerve cells and fibres that transmits nerve impulses between components of the body. This essay will explore the structure and functions of the system similarly as well as looking in depth at the neurons and how they communicate The system is split into two components, the central nervous system- which incorporates the brain and also the spinal cord. The…

with water, as its properties only allow certain components to flow through. The membrane contains small holes in which small molecules such as water can pass through. During this movement weather the water is moving in or out of the membrane the tonicity chances. It can either be hypertonic where the concentration is higher outside the cell and water moves out, or hypotonic where its lower outside the cell and water moves in. It will always be one of the two depending on the movement of…
