Osmosis

a cell inside of a hypotonic solution, the amount of a solute outside of the cell is less than the amount of solute inside the cell. The cell has more of the solute on the inside, which means the water will move into the cell. Water will move by osmosis to the area of greater solute concentration in order to balance the amount of solute and water. If a cell receives too much water as a result of a hypotonic environment, it may lyse, or burst, because of the influx of water. Plant cells…

Water is essential in keeping the body in balance. There are two significant compartments of the body that exchange fluids and electrolytes to maintain homeostasis, which are intracellular and extracellular. These two spaces continually interchange electrolytes, particles, and water to sustain the same pressure. (PP chap42 pg935) This paper will describe three machinimas that assists in maintaining homeostasis, four main categories of IV therapy, and nursing consideration in relation to infusing…

How is the membrane structure related to the transport of materials across the membrane? The membrane structure plays an important role in the transportation of materials across the membrane. The Cell membrane is a barrier that separates a cell from its surrounding environment. This is composed of Phospholipids, Proteins, Cholesterol and Carbohydrates. The Membrane Structure has a very important role in the transportation of materials across the membrane. The membrane of the cell is made up of…

Diffusion is high to low it involves no ATP nor does it need protein channels. Osmosis is a type of diffusion, it is the movement of water across a semipermeable membrane. Like diffusion there are no ATP but does need channels. There are a few terms to know when evaluating the levels of the solutes. Isotonic is when the levels are equal…

needed by organisms for growth and to manufacture various body substances. Every organism must keep it internal body fluids in balance in order to survive. Water uptake must balance water loss. Water- roots and root hair absorb water from the soil by osmosis. Roots are long and have a large surface area. Roots have thousand of root hairs behind the root tip. Root hairs increase the surface area, ensure close contract with soil to increase rate of water uptake and help penetrate all of the soil.…

Conclusion: As seen above by the graphs and data, an increase in molarity of NaCl solution results in a more negative percent change in mass. Therefore, there is a negative linear correlation between an increase in molarity and the mass of the potato; additionally, there is a strong correlation, as shown by the coefficient of determination (r2) of 0.965 in figure 4. For further evidence, the potato cubes that were soaked in the high molarity solution (0.5M and 0.4M) were much smaller and harder…

d. This lab clearly demonstrated that cells maximize surface area to volume ratios. With a greater surface area, diffusion takes place over a larger surface and is much more effective. Cells rely on movement of particles through diffusion to carry out activities. If cells were too big, diffusion would take too long because although there is still a large surface in which diffusion can occur, the large volume catches up to the surface area and requires more diffusion. The .5x.5x.5 cm agar cube…

Hannah Anderson Biology 111- Assignment #2-Properties of Water 1.) Hypothesis and Null Hypothesis: Hypothesis: Adding starch will keep from diffusing across the membrane. On the contrary, amylase will cause the starch molecules to break apart into smaller molecules of glucose allowing diffusion of glucose and Lugol’s reagent across the dialysis tubing. Null Hypothesis: Adding amylase to the beaker will have no effect on starch molecules and diffusion of the glucose and Lugol’s reagent across…

University of the people Written assignment unit 3 BIOL 1121 - AY2018-T1 Briefly describe the structure of a eukaryotic plasma membrane, identifying at least two component macromolecules and describing what their basic function is within the membrane. The eukaryotic plasma membrane is a phospholipids bilayer containing proteins and carbohydrates attached to the proteins and sterols. It is a fluid phospholipids bilayer embedded with proteins and glycoprotein. The phospholipids bilayer is…
