Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

osmotic activity‚ between the solution and a potato tuber of a given size. The purpose of this experiment is to demonstrate how living cells rely on osmosis‚ the diffusion of water. Osmosis is the movement of water molecules (H20) from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules‚ such as water‚ through but does not allow bigger

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

Living Alone or Living with Roommates Nowadays‚ a lot of attention has been drawn to the issue of whether college students should live alone outside the campus or live together with other roommates in the students’ dormitory. Opinions are divided on this issue. Those who are in favor of living with roommates have their own advantages. With several students sharing the same room‚ they could learn how to tolerate the difference between individuals. However‚ others argue that students who live outside

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially permeable

most families. The increase in population as well as the increase in land value and building costs‚ has resulted in the construction of many apartments especially in urban areas. There are some similarities as well as differences when we consider living in an apartment and in a house. In order to make an informed choice for one’s family‚ it is important to examine both the similarities as well as the differences of both options. Some of the similarities would be that it is possible to find a house

Living in a Dorm or Living at Home Have you ever enjoyed the whole sleepless night in a dorm with your friends? Students in dorms can do everything they want‚ go everywhere they like‚ and they can escape stresses from their parents and their own house. College is a stepping stone from high school to the real world. College is also a time for students who want to live independently and self-reliantly. College is usually associated with dorm life. Instead of living with their parents‚ most college
