B4.2 Plant Nutrition (Combined Science)

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. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity.

Here are the key terms and some definitions: Key Terms B4.2

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:

Also IB 2.9 & 8.3 – Photosynthesis Part 1: Introduction to photosynthesis including ways to measure the rate and limiting factors of photosynthesis in 10m from Dan Rott. Or here is Photosynthesis part 1 of a series of tutorials, specific to IB Biology from Alex Lee.

Click on ‘Photosynthesis’ to see a detailed Interactive Animation from Wiley that covers all the reactions of Photosynthesis.

LIGHT DEPENDENT REACTIONS

Two fantastic animated tutorials from McGraw Hill Education – photosynthesis electron transport and  photophosporylation (cyclic & non-cyclic) – both are a bit more detailed than we need but they’re good.

This animation also shows how PSII and PSI reduce NADP: here.

This short, simple animation is a good summary of photosynthetic electron transport. as is this one from Biology 231.

Photosynthesis – Light-dependent Stage, an 8m video from Mr Exham or here is IB 2.9 & 8.3 – Photosynthesis Part 2: LDR in 9m from Dan Rott.

Mr W sings Photosynthesis – the LDR.

LIGHT INDEPENDENT REACTIONS (CALVIN CYCLE)

The Calvin cycle – a fantastic animated tutorial from McGraw Hill Education.

And here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesisfrom Sinauer Associates.

Photosynthesis – Light-independent stage, a 5m video from Mr Exham, and here is a 5m TED-Ed lesson: Nature’s smallest factory: The Calvin cycle and this is IB 2.9 & 8.3 Photosynthesis Part 3: LIR in 11m from Dan Rott.

Mr W sings Photosynthesis – the LIR.

CALVIN’S EXPERIMENT

BioNInja has a great summary of the lollipop experiment, including a nice animation.

The Calvin Experiments – an animation that takes you through the 3 techniques he used to investigate the LIR.

Calvin’s Experiments (2016) IB Biology, a 10m video from Alex Lee.

REVIEW

How do photosynthesis and cellular respiration compare – a Virtual Lab animation and assessment.

Key terms as flashcards from Quizlet (you also can test yourself in a number of ways):

IB Biology Photosynthesis 2015 from Bob Smullen

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).

PRACTICAL – Rate of Photosynthesis

Here is a simple Rates of Photosynthesis lab simulation from Reading University and here are two at Photosynthesis Virtual Lab.

DPIP practical simulation from Lab Bench.

PRESCRIBED PRACTICAL 4 – Chromatography of plant pigments

Separation of photosynthetic pigments by chromatograph

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:

 SAPS sheet 10 – TLC

Chromatographs – notes from BioNinja

Plant pigment chromatography, a LabBench Activity from Pearson

9C Plants & Photosynthesis

A nice short introduction to Photosynthesis (from Twig World)

Appalling song but over 1.7 million hits!
