Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

sugar the mass of beetroot decreased. This happened because water moved from the inside of the beetroot‚ where there was a high water potential into the sugar solution‚ which had a lower water potential. In the other four beakers where the concentration of sugar solution was less‚ the mass of the beetroot increased. This happened because water moved from the dilute sugar solution where there was a high water potential‚ into the beetroot. The percentage increase in the mass of beetroot increased as the

OUT OF COOKED BEETROOT? PLAN Hypothesis Temperature has an effect on the leaking of the colour from beetroot. This means that as the temperature is altered there will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure of beetroot‚ it will be

Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature

Pre-lab questions: 1. Algae belong to what Kingdom? They belong to the Kingdom Protista. 2. What are the three types of multicellular algae? The three types if multicellular algae are chlorophyta which are green algae‚ phaeophyta which are brown algae‚ and rhodophyta which are red algae. 3. Are algae autotrophs or heterotrophs? Algae are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize
