    Operational definition of photosynthesis: photosynthesis is a process whereby the Hydrilla sp. in sodium hydrogen carbonate solution produces air bubbles.
    It is shown by the ................RV....................... and is influenced by ............MV...............

    thank you for the video sir, it's really helpful! the pdf link in the description is for the spm 2022 amali instead though, hope you can share the 2024 one because i want to refer 🙏 once again thank you very much sir!!!

    Operational definition of rate of photosynthesis : Rate of photosynthesis is the number of air bubble produced by Hydrilla sp in .....% sodium hydrogen carbonate solution per minute.

    10:33 sir this one can put " rate of photosynthesis is inversely proportional to light intensity as more photolysis of water causes more oxygen gas to be released" ?

      @davinbiology  Місяць тому +6

      bio cannot write inversely proportional ya, must say as.... increases ..... decreases

    Hi sir, just wanna ask when do we need to use bar chart and line graph? I saw some trials use bar chart, some use line graph

    • @davinbiology
      @davinbiology  Місяць тому +6

      Bar graph is used when the MV is discountinuous means not something u can meausre like presence of sulphuric acid. Distance of light source is cm, got unit and can measure so is line graph

    how about the hypothesis

    • @davinbiology
      @davinbiology  Місяць тому +1

      As the distance of light source from Hydrilla sp. increases, the number of air bubbles decreases

      no it's not, the points has to connect, free hand draw the garph

    Teacher are you sure that the table doesn’t need calculations? Because whenever we do experiment in class our bio teacher always says that it’s mandatory to have the calculation shown in the table

    • @davinbiology

      @AngeloAmrish yes, marks are only given for the correct answer. You do not need to show working as its only 1 mark

    Teacher if we sketch the diagram of the apparatus,do we have to sketch using pen as they will scan the paper right

    • @alphathelearner8902
      @alphathelearner8902 Місяць тому +1

      According to my understanding you should sketch in pencil and label with pen

    will the exam ask aim and problem statement?

    • @davinbiology
      @davinbiology  Місяць тому +6

      Aim wont ask, aim is mentioned in the question, to identify effect of MV on RV.
      Problem statement maybe - how MV effect RV?

    Teacher how to handle the MV?

    • @davinbiology
      @davinbiology  Місяць тому

      @owenteoh2179 using diffrenet MV at different value. For example, use different distance of light source 20cm 30cm 40cm.
