    1) Use different samples of food and ignite them under a test tube containing water with a thermometer(at least 1/3rd immered). use the method for each food sample, like separately for carbohydrate, fat, and protein. Record the temperature increase in each test tube by burning the food sample...

    that i know. want you to identify the plumule and radicle (shown in q no. 2) http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20O%20Level/Biology%20(5090)/5090_w10_qp_62.pdf

    I got a feeling that the upper part is plumule and the part in the center is radicle, what do you say?

    yea but still, some pictures do show that plumule and radicle grow from the top. Here there are 2 possibilities and one would not risk in guessing so i want this clarified! Plus, there's no hint in the mark scheme.

    Maybe they come out from the same point in epigeal germination, and not in hypogeal germination ..

    Relative velocity is that chapter which you can't study by yourself. Besides, if you don't get the concept from that Add math book, then other notes would be useless, most likely. MY advice: leave relative velocity, practise other chapters instead.

    This is totally shit, I've seen pictures-some show they come out from the same point on the testa, while others show that plumule grow out from the top, and radicle from the bottom/middle of the testa.

    During anaerobic respiration, bubbles are produced which when burst give off CO2. So CO2 then can easily go through the tube to lime water and turn it milky.

    And hey, do plumule and radicle originate from the same point on the seed, or does plumule come out from the top of the testa, and radicle from the middle/bottom?
