The Effects of Various Chemicals and Temperature on Membrane Permeability of Beetroot Name: Ghazal Daneshfar E-mail: GDANES200@caledonian.ac.uk Student ID: S1312108 INTRODUCTION The cell membrane consists of mostly phospholipids and proteins which gives the cell its selectively permeable nature. The function and permeability of the cell membrane depends on its whole structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out

membranes of Beetroot cells. OBJECTIVES To investigate whether temperature will damage and denature the permeability of plasma membrane. HYPOTHESIS An increase in temperature will damage and denature the permeability of plasma membrane. INTRODUCTIONS Beetroot The beet (Beta vulgaris) is a plant in the Chenopodiaceae family. It is best known in its numerous cultivated varieties‚ the most well known of which is probably the red or purple root vegetable known as the beetroot or garden beet

environment. This usually means the cell that made the vacuole is dead. Variables. Age of beetroot. The age of the beetroot needs to be controlled as to prevent inaccuracies. The older the beetroot the more betacyanin and anthocyanins molecules present. This will therefore make the experiment unfair‚ because the more pigment molecules present the more pigment molecules that can move out of the cell. Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have

membrane. These will be distilled water‚ sucrose‚ sodium hydroxide‚ hydrochloric acid‚ ethanol and boiled water. The treatments include immersion in these solutions‚ and exposure to high temperature. The tissue used is from the taproot of a beetroot‚ and the effect on the membrane’s permeability assessed by the amount of pigment leakage that occurs. Hypothesis ========== I predict that the most damage to the membrane will be caused by the acid or the boiling water. I think

Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane.

Beetroot Beetroot is a brilliantly versatile veggie. There are many ways to eat it including the traditional pickled beetroot but also more modern recipes such as marinated beetroot with grilled goat’s cheese and creamy beetroot risotto. To grow beetroot‚ sow 2 seeds every 10cm (4 inches) into a 2cm (0.75inch) deep trench. The children will enjoy using a stick to make the trench

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)

Research and Evidence-Based Practice in Nursing In this discussion board I will discuss research and evidence-based practice in nursing. I will give examples of each‚ as well as a research and clinical question pertaining to nursing. Research and evidence-based practice are important for nurses because they help to find the most safe and effective way to care for patients. Research in nursing is used to aid in answering a nursing related issue (LoBiondo-Wood & Haber‚ 2014). Nursing research is
