Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

even though the poet and his mother are having a good time peeling potatoes‚ his mother is ill and they are brought to their senses that the happy times will soon be brought to an end. 2. The potato is an important symbol in Ireland because of its value as a food staple and reminder of the terrible potato famine in the 19th century. What personal symbolic value does it have in this poem? In this poem the potatoe is a symbol of time shared with the poets mother‚ time when it is just him and his

The effect of osmosis on artificial cells with different concentrations of sucrose Alex McRae Biology 120-902 Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 mcraeal@mail.gvsu.edu Abstract In this study‚ we tested the validity of osmosis in artificial animal cells. Osmosis is the diffusion of free water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different

Diffusion & Osmosis 9/16/14-9/19/14; Jessica Bullock‚ Andrew Buchholz‚ Kristamae Masiclat TITLE: Different Ways to Express Diffusion and Osmosis INTRODUCTION: Diffusion is the spontaneous movement of a substance down its concentration gradient‚ from a region where it is more concentrated to a region where it is less concentrated. Osmosis is the diffusion of water across a selectively permeable membrane. The objective of this lab is to observe the different effects of diffusion and osmosis through

Introduction The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic‚ hypertonic‚ and isotonic. When in comparison

The Main Body Tissues Introduction Tissue just means a group of cells that together carry out a particular job in your body. There are four different types of tissue within the human body. This consists of the connective tissue‚ the epithelial tissue‚ the muscle tissue and the nervous tissue. Each of these tissues are vital for our bodies and each tissue has a very important role to fulfil. Epithelial tissue Epithelial tissue protects your body from moisture loss‚ bacteria‚
