Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root. First of

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

THE EFFECT OF CHANGE IN pH ON THE ACTIVITY OF ENZYMES Introduction: Enzymes are catalysts that speed up‚ and control chemical reactions within a cell and break down complex molecules into smaller ones. Some of the chemical reactions that take place in the body produce toxic by-products which need to be converted. The liver produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim:

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate
