    For the control I said to fill a test-tube with 10cm^3 of hydrogen peroxide without the potato to check that it didn't decompose by itself. Think that may be wrong though...

    As for the drawing, I didn't draw the entire picture as I ran out of time, I just drew the vascular bundle without the surrounding cells.

    What did you guys put as the problem with the way the oxygen was measured? Got confused at that question

    I didn't draw the surrounding cells as it said not to draw individual cells.
    For the measurement of oxygen I said record with a video and take note or collect the oxygen produced.

    I thought you were meant to boil the potato for the control so that the enzyme Catalase in the potato was denatured meaning you could prove that it was those enzymes causing the reaction idk that's just what I wrote
