Beetroot Practical 2.8 An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim

use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions: 1. Describe

INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

I Watch Paint Dry I woke up early that fateful morning. It wasn’t any ordinary day; it was the day I finally repaint my room! I was so excited that I didn’t even have breakfast‚ maybe that’s what caused my unplanned “trip”. I quickly got started and finished the job in just an hour. Is it really boring watching paint dry? ‚ Said my hungry and slightly delusional mind. I guess I’ll give it a shot‚ I guess it’ll be fun!. As I look around my room‚ I noticed something. I noticed something that

What is Cancer? All living things are comprised of a variety of cells‚ such as kidney cells‚ brain cells and skin cells. Cancer develops when a particular cell mutates‚ then begins to grow and divide. Eventually‚ these cells form a mass called a malignant tumor‚ which often starts to invade surrounding tissue and organs. Super Foods It is thought that up to one third of cancer related deaths could be diet related. Many of the foods we eat today can in fact be harmful to the cells in our bodies

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

were 2‚4‚7‚9 and 10. All of these solutions affected the beetroot‚ but the most acidic solutions were the ones that did the most damage to the membrane. This is because the ph affects the proteins within the phospho lipid bi-layer. The acidic ph breaks the hydrogen bonds therefore denaturing the proteins and allowing beetroot pigment to secrete form the cell. 7. The ethanol solutions that were used were 11%‚ 25% and 50% ethanol. The beetroot cell was almost immediately affected by the 50% alcohol

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors
