Dried scales will be removed and the bottom plate scraped‚ leaving the ring of root primordia intact‚ to stimulate root growth. Onions will be suspended to allow germination in 220-mL glass jars half-filled with mineral water for 72h in a 12h light/12h dark cycle at room temperature. For each series‚ the onion with the poorest root growth will be discarded. The onions will then be transferred to glass jars containing 0.625‚ 1.25‚ 2.5‚ 5‚ and 10 mg/mL of T. indica methanol leaf extracts to which

INSECTICIDAL EFFECT OF ALLIUM CEPA (ONION) AND ALLIUM SATIVUM (GARLIC) ON MOSQUITOES An investigatory project in partial fulfilment of the Requirement in Research II THE PROBLEM AND ITS BACKGROUND Introduction Nowadays‚ we are experiencing diseases which is caused by insects like mosquito. To name some are Dengue‚ Hemorrhagic Fever‚ and Malaria wherein if not treated early it can cause death. Mosquitoes are all around the corner of our environment. They are not that big but can cut

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

Osmosis Egg Lab I. Introduction The reason for doing this lab was to see the process of osmosis. Osmosis is diffusion from a high concretion to a low concentration across a cell membrane. The cell membrane was represented by an egg without a shell. II. Hypothesis The egg that will placed in the distilled water will swell like a balloon. This is because distilled water is a hypotonic solution which makes water go in a cell (the egg without a shell) and make it swell. The egg that will placed

Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in
