    Determining the Rate of Osmosis through a Semi-Permeable Membrane Schneider‚ Justin* Sec 16 and Thomas Hudson Introduction Water is the principle solvent in cells. There are three conditions that a cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it

    water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract a ‘cloud’ of polar water molecules around them. The cloud is held by weak chemical bonds that include

    Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions. This project

    Absorption of isolated chloroplasts To test absorption of isolated chloroplasts from spinach absorption readings were taken at a series of different wavelengths. Absorption Maxima of the isolated chloroplasts were observed at wavelengths of 440 and 680 with corresponding absorbance values of 0.792 and 0.589 were noted (Fig 1.). Absorption minima of the isolated chloroplasts was noted at a wavelength of 580 at an absorption of 0.291 (Fig 1.). This indicated that green light is reflected strongly

    Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The unknown element

    Osmosis Lab Conclusion The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled

    DIFFUSION AND OSMOSIS Chapter 3 of your textbook explains diffusion and osmosis. Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration. The force behind the movement is heat or kinetic energy (also called Brownian motion). Diffusion occurs when you spill water on the carpet floor and it spreads out‚ or when you open a bottle of perfume and it leaves the bottle and spreads throughout the air in the room. Osmosis is a similar
