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...............
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. 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!!!
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" ?
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
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

Very helpful, thank you teacher I hope we all can get great marks for bio amali

Sorry i posted the wrong file. I've updated it already
One of the best videos on this experiment! Thank you so much 🎉
Thank you for you support!! it really means a lot🫶🏻

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 alright tq sir

@AngeloAmrish yes, marks are only given for the correct answer. You do not need to show working as its only 1 mark
Graph is meant to be best fit line right sir?
no it's not, the points has to connect, free hand draw the garph
@@davinbiology okay thank you very much ❤
how about the hypothesis
As the distance of light source from Hydrilla sp. increases, the number of air bubbles decreases
Teacher if we sketch the diagram of the apparatus,do we have to sketch using pen as they will scan the paper right
According to my understanding you should sketch in pencil and label with pen
will the exam ask aim and problem statement?
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?
@owenteoh2179 using diffrenet MV at different value. For example, use different distance of light source 20cm 30cm 40cm.
Ight thank you teacher
ahhh thankyou sir….its really helpfull and really easy to understand u just made me like biology even more❤️🩹
