The Effect of temperature on beetroot This experiment is designed to investigate the effect of varying temperature (centigrade) on beetroot and its cells. My earlier experiment suggest that as temperature increases the integrity of the beetroot cell membrane will be destroyed and a subsequent release of beetroot pigment will be released into its surrounding milieu(in this case distilled water). In the experiment I will examine if my hypothesis (above) is correct. In order to conduct this experiment

Why does belatin leak out of cooked Beetroot? In cooked beetroot‚ the water or food would become stained due to its leakage of betalin (the redish-purple pigment). Betalin is found in the vacuole of beetroot cell. The leakage may have been caused by something happening in the cell membrane of the beetroot – concerning the proteins embedded in the phospholipid layer. The study will require the experiment of different temperatures of water and to find out which in temperature causes the most leakage

The poem “The Mouth” written by bpNichol is littered with ambiguity. You could pick any line in any stanza and find something with a double meaning. In the second stanza‚ Nichol writes: “You were never supposed to talk when it was full. It was better to keep it shut if you had nothing to say. You were never supposed to shoot it off. It was better to be seen than heard.” Besides the obvious oral fixation he has‚ what does he mean when he says this? It seems as though he has been silenced before in

BEETROOT PIGMENTS - and membranes – These pigments are betalain pigments (not‚ as often thought‚ anthocyanins)‚ which they replace in some organisms. They are named after the Beet family of plants (Beta) but are also found in fungi (Fly Agaric - the red‚ spotted one!). In petals they presumably attract pollinating insects and may be present in seeds/fruits to encourage birds to eat them and so disperse the seeds. Man has selected for colour in beetroot‚ both because

Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes

Write down your idea as a hypothesis that you can test‚ and support your idea with biological knowledge. Hypothesis “The greater the concentration
