Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

Transformation of Amyloplasts into Chloroplasts in Potato Tubers’ Received for publication November 9‚ 1983 and in revised form January 19‚ 1984 YU S. ZHU‚ DENISE L. MERKLE-LEHMAN‚ SHAIN D. KUNG* Department of Biological Sciences‚ University of Maryland Baltimore County‚ Catonsville‚ Maryland 21228 ABSTRACT The transformation of amyloplast into chloroplasts in potato (Solawum tuberosum L.) tuber tissue can be induced by light. Excised potato tuber discs illuminated with white light of 3000

Conclusion The research question that I asked myself before the experiment was “What is the osmotic potential of potato?” The answer I got after the experiment was that the osmotic potential of potato is very high because this experiment exactly showed what happened when there is Osmosis present and the following information will prove it. Our results greatly showed that there has been osmosis present. Osmosis is the diffusion of water through a partially permeable membrane from a region of lower

Bad eating habits are common. It is easy to operate on automatic when it comes to food. Living in a fast-paced society often makes it so you have to eat on the run‚ skip meals‚ eat whatever is fast and easy or use food to relieve stress. We eat a lot of bad foods everyday‚ but we don’t think what impact on our health it makes. I watch a video about Top 10 Bad Foods and now I can say which products and drinks disappear forever from my diet. So Top 10 Bad Foods are : 1. Soda 2. Doughnuts

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

of salt concentration on potatoes. Scope In this investigation three square pieces of potato were placed into individual beakers containing different salt concentrations of 0%‚ 10% and 20% and observed for 120min. Hypothesis The theory behind this experiment was that the piece of potato placed into the 0% salt solution would increase in weight and size as it is a hypertonic solution. The pieces of potato placed into the 10% and 20% salt solution would theoretically decrease in weight and size

activity between the solution and a potato chip of a given size. The potato chips were cut to size‚ then added to a water based sugar solution‚ where the variable was the amount of sugar added. The potato chips were cut to size by a potato chip cutter‚ leaving them all roughly the same size‚ then further adaptations to the potatoes were made using a sharp knife in order to allow the potatoes to be re-sized to a more accurate size in comparison to the other potato chips.

from potato starch – extracting starch In this activity you are going to extract starch from potatoes. This starch can be used to make a plastic. A similar process is used in industry to extract starch‚ which is then used in a number of products‚ including food and packaging.
