Investigating Osmosis In Potato Cells Apparatus: The apparatus used in this experiment were: 1) 5 beakers‚ 2) 3 large potatoes (same type)‚ 3) 15 pieces of potato without skin (roughly the same size)‚ 4) 10 pins‚ 5) 50ml of distilled water‚ 6) 50ml salt solution 0.50‚ 7) 50ml salt solution 1.00‚ 8) 50ml salt solution 1.50‚ 9) 50ml salt solution 2.00 10) Scales‚ 11) Knife‚ 12) chopping board‚ 13) cork borer‚ Prediction & Theory: When the potato pieces are put in to the water there

occur by moving water through the semi-permeable membranes. If the concentration of sucrose in the solution is less than the concentration of sucrose found in the potato‚ then the potato would decrease in mass. The opposite would occur as well‚ if the concentration of sucrose in the solution is more than that of the potato‚ then the potato would expand and gain in mass. In conducting this as an

Fetal tissue research is an important aspect of medical research. Fetal tissues can be obtained from many places‚ including hospitals‚ tissue banks‚ and abortion clinics. Conducting fetal tissue research allows us to further our education concerning diseases‚ vaccinations‚ and birth defects. Despite the importance of fetal tissue research‚ it raises many controversies regarding ethical issues. Many people believe that fetal tissue research should be illegal because it goes against their morals

Practical 1 - Investigation into size and scale of microscopic tissues This practical focuses on microscope technique and using graticules and stage micrometers to determine size and scale in biological cells and tissues. Intended learning outcomes By the end of this practical you should be able to: • Use a microscope fitted with an eyepiece graticule and stage micrometer • Calibrate the eyepiece graticule using the stage micrometer • Use the calibrated graticule to determine the actual

GCSE - Human Physiology and Health An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water

April 2nd‚ 2015 Organ and Tissue Donation Should Be Mandatory Once Deceased “You are going to need an organ transplant”. Many Canadians face this reality every day. The problem is‚ not all of them will receive a transplant. According to the Trillium Gift of Life unnecessary comma Network‚ there are 1597 people in Ontario waiting for transplants but only 116 donors available as of March 26th‚ 2015 (Trillium Gift of Life Network - Ontario’s Organ and Tissue Donation Agency : Public Reporting)
