    Northern Kentucky University BIO 150L: Introduction to Biology I Instructor: Dr. Bethany Bowling Osmosis and Diffusion Report Estimating the Osmolarity of Plant Cells--Potato YAO ZHANG 03/26/2012 Introduction: It is undeniable that all cells have the kinetic energy. It will led the cells move randomly around to others. For this molecular movement‚ there are two results that might happen. Diffusion is one of them. Diffusion is the movement of molecules that between the

    concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain specific requirements for survival. Large amounts of water are absorbed by root hairs and are then distributed across the cells of plants by the process of osmosis; water being essential to

    I am going to investigate osmosis when potato is placed in different  concentrations of sucrose. I am aiming to witness osmosis in 5  different concentrations of sucrose. I will use 5 varying  concentrations so that I have a wider spread to compare the results‚  and check that I don’t have any anomalies  Prediction  Osmosis is the process of diffusion of water molecules from a weaker  solution into a stronger solution‚ through a semi permeable membrane.  The tiny pores in the membrane

    Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment‚ its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)

    Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

    The aim of the sixteenth of November experiments was to observe how three different solutions with various sucrose concentration influenced osmosis in relation to three onion cells and the impact on the cells structure. A small square of a red onion skin (membrane) was observed under a microscope at high power (X40) magnification. The observation showed a large number of onion cells. The structure of one onion cell had a general rectangular shape with a developed cell wall‚ which gives the rectangular

    of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur
