Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately and then

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process by which cells harvest energy that is stored in food. The three stages are glycolysis‚ citric acid cycle‚ and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis which mean splitting

Associate Program Material – Heather Earnhardt Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three

Cell Organelle Worksheet Organelle Nucleus Where found (plant/animal/both) In animals it’s in the center of the cell while in plants it’s found in the cytoplasm. What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages. Organelle Nucleolus Where found (plant/animal/both) For both animal and plants it’s within the nucleus of the

effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly objectively using

typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers (nm)) thick‚ which is partially permeable. It consists mostly of lipids and proteins. The lipids found in cell membranes

Cell Transport Mechanisms and Permeability 1 EXERCISE 1 OBJECTIVES 1. To define the following terms: differential permeability‚ passive and active processes of transport‚ diffusion (simple diffusion‚ facilitated dif- fusion‚ and osmosis)‚ solute pump‚ pinocytosis‚ and phagocytosis. 2. To describe the processes that account for the movement of sub- stances across the plasma membrane‚ and to indicate the driving force for each. 3. To determine which way substances will move passively

“Cell Transport Lab” Hypothesis: I hypothesis that there will be a movement of molecules out of the egg‚ and will move into the water solution. Osmosis will occur within the egg‚ and in the process the molecules of the egg will diffuse.
