mass of potato Introduction- diffusion is a passive transport where molecules move from areas of higher concentration to areas of low concentrations. Although the molecule ’s movement is random‚ equilibrium is being sought out. Osmosis is a type of diffusion only It involves water. In osmosis water diffuses from the area of high concentration to an area of low concentration‚ to diffuse the more molecule rich side. Because cells have selectively permeable membranes‚ meaning certain substances can

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose 1. Put

ORGANIC MATTER AND INORGANIC MATTE Organic matter is that which is living or has been alive‚ e.g. wood or coal. Inorganic matter is that which is not living and never has been alive‚ e.g. water or iron. Inorganic substances can be built up into organic compounds by living organisms. All living matter is made up of small units called cells. Some organisms‚ such as bacteria‚ consist of one single cell; others‚ like human beings‚ consist of many hundreds of millions of cells‚ all functioning together

ASPECT 1: Defining the Problem and Selecting Variables CELLS are the basic unit of structure in all organisms and the smallest unit of life. All living things are made of cells. Multicellular organisms (humans) are composed of many cells. Unicellular organisms (bacteria) are composed of only one cell. Existing cells come from other pre-existing cells and cannot be created from non-living materials. All cells are surrounded with membrane called CELL MEMBRANE (PLASMA MEMBRANE). Plasma membrane is semipermeable
