Hydrochloric acid is also needed to "kill the cell", this preserves the stage of mitosis the cell is in, STOPPING MITOSIS. In addition it SEPARATES THE CELLS from the tissue sample collected of the root tips, so ensures it can be squashed, and flattened to A SINGLE THING LAYER OF CELLS, SO LIGHT CAN PASS THROUGH.

10:43 do you seriously have to know this level of detail for each type of reaction to get marks because it seems so excessive. in my booklet it's quite basic, for a temp. change reaction it's just stuff like add the solution to boiling tubes, boil at different temps, add enzyme to tubes and then test rate of production of gas. stuff like that, but obviously with more detail based on what's used in the question. or is that not enough to know, and do you have to know things like what enzymes would be used for what, past the basic knowledge of enzymes such as amylase?

@@jakemorgan7242 i found out from other students and teachers that when we go for the practicals mainly for aqa they give us a sheet which is instructions on how to perform the practicals and we dont need to memorise so much of the values e.g. 0.5 mol/dm3 we would instead get given the values to match the scenario i may be wrong but this is what other teachers have told me

Hi Miss Estruch, I came across an AQA past paper question that was specifically about how to isolate a sample of chloroplasts from cells. It had a four mark method. Is this a practical or is it part of the spec somewhere else? It made me panicked that perhaps I did need to know some of the practical methods in their entirety! Thank you!
