8.3 Photosynthesis

BioKnowledgy 8.3 Photosynthesis AHL from Chris Paine.

Find a video lesson on this sub-topic at Dan Rott videos.

8.2 Photosynthesis essay qus

Paul Andersen explains the process of Photosynthesis in a 12m 27s tutorial:

Or here is part 1 of a series of tutorials, specific to IB Biology.

A short, simple animation to show photosynthetic electron transport and here is an animated video that explains the LDR.

Click on ‘Photosynthesis’ to see an Interactive Animation from Wiley or here are some fantastic animated tutorials from McGraw Hill Education – Photophosporylation (cyclic & non-cyclic) – a bit more detailed than we need but its good, photosynthesis electron transport & ATP synthesis &  the Calvin cycle.

Finally, here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesis – from Sinauer Associates.

Mr W sings Photosynthesis – the LDR and the LIR.

2.9 Photosynthesis

BioKnowledgy 2.9 Photosynthesis from Chris Paine.

A good, general overview of Photosynthesis (4m 52s):

In Crash Course Biology #8 – Photosynthesis, Hank explains, well, photosynthesis.

The simple story of photosynthesis and food from TED-Ed. Find a video lesson on this sub-topic at Dan Rott videos, or many assessment statements are covered by Stephanie Castle (with more being added all the time).

COMPULSORY PRACTICAL 4 – separation of photosynthetic pigments by chromatography

One way to do it is this: chlorophyll chromatography and an alternative method includes how to calculate Rf values. Hopefully the final result will be this. An alternative method:

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. Powerpoints can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it.

What’s in a molecule? – The science of macaroni salad from TED-Ed (3m 15s).

This powerpoint covers both Plant and Animal nutrition:
