    Biology 107 Section 1 11/4/13 Diffusion & Osmosis Introduction The purpose in this experiment was to estimate the osmolarity of potato tuber and celery cells by change of weight.Pieces of potato tuber and celery would be incubated in different sucrose solutions to find out the molarity at which weight of potato and celery tissues do not change. My hypothesis was that the Table 1: Group Data for Experiment:Estimating Osmolarity by Change in Weight Table

    environment from my awareness or don’t hear a story my roommate tells me while checking Facebook on the computer. However‚ when hearing my name from a distance‚ I can automatically switch gears and will listen to what is being said. The reason for this is selective attention. When on the mound during a softball game‚ I selectively pay attention to the pitch I am about the throw and how I’m going to go about that pitch. I process information from one part of the environment and exclude all the other parts. I

    DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

    Part 1 Part 1 of the experiment investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower

    13 THE MEMBRANES OF DIFFERENT TYPES OF CELLS ARE INVOLVED IN MANY DIFFERENT FUNCTIONS – 25 MARKS Membranes are found in all organisms‚ around and within cells. They control the movements in and out of cells‚ as well as protecting cells. They also allow different functions to occur. They have the same basic structure called the plasma membrane. All plasma membranes‚ around or inside cells have a same phospholipid bilayer structure. Phospholipids contribute to the flexibility of membranes and transfer
