Thank you SO SO much habiba for this. Definitely top 3 habiba comebacks (top 1 possibly?🤔)I didn’t wanna comment until I watched the whole video (1.5 speed due to my ipad kid attention span) and analyzed it frame by frame. You got the syllabus, information well organized and adequate, timestamps which are so helpful (minus the 21:15 one for calvin cycle but that doesn’t affect the quality of the Video really) and the marking schemes on the slides which’s is just so juicy and scrumptious. Seeing more past paper hacks/ common questions would be just the cherry on top. I don’t think you can comprehend how absolutely helpfully this is. I’m definitely looking forward for more chapters, and thank u again for the description 😈😏😏. الله يجعلها بميزان حسناتك🙏 And happy early birthday 🆘🆘🚨🚨‼️‼️😍😍😘⭕️⭕️🔛🔝

Alrightmira

For DCPIP:
In the current syllabus, they'll ask for DCPIP to test rate of photosynthesis and respiration

to get marks on a question asking for investigations with dcpip for rate of photosynthesis, you must write:
- extract chloroplast by grinding leaves, dissolving with small amounts of solvents and filtering (1 mark for method of chloroplast extraction)
- add DCPIP to chloroplast
