to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic: Having reduced pressure or tone‚ in particular. * Isotonic solution: a solution having the same osmotic pressure 3. Explain the similarities

would be hypertonic. This projection was initially made through deduction. Syrup is a highly viscous solution in comparison to dihydrogen monoxide; however‚ it is mundane erudition that syrup contains dihydrogen monoxide. Most living organisms are virtually entirely composed of dihydrogen monoxide‚ such as humans‚ so it was surmised chickens were equipollent. Hence‚ it was deduced that there would be more dihydrogen monoxide in the egg‚ than in the syrup-making the maple syrup hypertonic. Dihydrogen

story that caused the corn fields to die. The first mistake Michael made was to add the additional fertilizer to the crops. The extra fertilizer around the roots of the corn produced a hypertonic environment. The cells lost water because of the excessive fertilizer. The extra fertilizer caused the cell to turn hypertonic to the plant cell. This made the water diffuse from the plant cells into the soil by the process of OSMOSIS and the cells began to get smaller. The water would have eventually left

3. Describe the differences between animal and plant cells. Although plant and animal cells both have mitochondria‚ cytoplasm‚ and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells‚ as well as most eukaryotic cells. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles‚ but their functions are quite different. The purpose of vacuoles in

Introduction This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the

also a form of passive transport.Osmosis occurs when water molecules diffuse across the cell membrane from an area of higher solute concentration to an area of lower solute concentration. There are three relative concentrations of solutions. Hypertonic solutions yield a higher concentration than that of the cell.Hypotonic solutions have a lower concentration and isotonic solution has an equal concentration. Method: The eggs were soaked in vinegar for 48 hours. At the end of this period the
