Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

on the amount of 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

The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important

I have been asked to investigate the effects of osmosis on potato cell sap. I will test potato cylinders in different strengths of sucrose solution and record any results in a table. I will then analyse my findings and work out the isotonic point of the potato cell sap. Prediction I have looked at my scientific knowledge from the background theory I carried out and I will base my prediction upon this information. In this experiment‚ I expect the different concentrations to show fairly noticeable

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

land of Bangladesh. In last few decades‚ the demand of potato is increasing rapidly. As a developing country‚ the people of Bangladesh are not so affluent. That’s why they prefer potato to rice or wheat. The demand of potato is thus increasing as it is cheaper than the other two horticultural product rice and wheat. Last year‚ the production of potato is massive. But‚ that huge production makes a little impact on the price level of potato. The price at the point of production is relevantly low
