    state of ppl who grinded unit 3....

    name the final products of the light stage of photosynthesis
    IAA is a growth regulator, in your experiment how did you measure the growth of the plant.
    draw a graph to show enzyme action and effect of temprature on it (just say how it will go tbh but its a likely question)

    final products of the light stage: oxygen, nadh, atp?
    to measure the growth of the plant you photocopy graph paper onto acetate and stick it on the inside of the petri dish and use that to measure the length of th plant
    enzyme action is low until 27degrees.. no i'm getting mixed up with pH. it increases gradually as it gets closer to 27degrees and decreases after that.

    particles of the bone, is that like osteoblasts, calcium.. what else is ther?
    dont rly know how the human embryo forms.

    explain the formation of both male & female plant gametes
