Control process Beetroot hears: The identical size car park beets raiseament be used passim the investigate this is to take in that the impact of the temperature on every seek testament deterrent the same, i.e. if having a bigger beetroot model less make ups go away be released into the test tube at lower temperature, or having a smaller beetroot take more rouge will be released into the test tube. This phantasm will neuter the results of the experiment at large. Therefore it is of import to promise the sample sizes are the same. Temperature: As temperature will shine the beetroot mobile phone membrane, I will keep the temperature unceasing throughout the experiment by using a water system toilet and measuring the desired temperature using a thermometer. PH: I will make sure that the pH is stable (constant) and all the same the temperature varies this is to be done by using devotee in every test tube so as to behave pH balance for each beetroot sampl e and mark off that pH does not become a variable. PH is pristine for maintaining the integrity of the cell membrane as integral proteins gage denature upon change in pH. Also, presumably the buffer will have the right concentrations of salt or electrolytes (ion such as Na, K, Ca, etc.
)- that is, the solution and the beetroot cells must be isotonic, so the buffer must be used for each trial-to turn back that the beetroot cell doesnt lyse due to being placed in hypotonic solution Additional controls Time: Amount of condemnation beetroot sample remains in a test tube must remain the same for each trial Cutting Beetroo t: Results could be affected by blusher re! leased due to cutting of beetroot, so wash of initial pigment (excess juice) at the start.
