Plant Anatomy – microscope slides and sample questions.
9.1 Transport in the Xylem of Plants
9.1 transport in the xylem of plants from Bob Smullen
Fantastic animated tutorials from McGraw Hill Education – Water Uptake, Mineral Uptake.
A 13m 43s video lesson covering all of 9.1 from Dan Rott:
Paul Andersen explains how nutrients and water are transported in plants in Plant Nutrition & Transport.
Here’s a simple transpiration animation & here’s a great animation in which you can change the factors that affect the rate of transpiration.
9.2 Transport in the Phloem of Plants
9.2 transport in the phloem of plants from Bob Smullen
A 10m 22s video lesson covering all of 9.2 from Dan Rott:
Paul Andersen explains how nutrients and water are transported in plants in Plant Nutrition & Transport.
A fantastic animated tutorial from McGraw Hill Education on Phloem loading (how sucrose is transported).
8.1 Metabolism
BioKnowledgy 8.1 Metabolism (AHL) from Chris Paine.
Find a video lesson on this sub-topic at Dan Rott videos.
Activation Energy:
Mr Bozeman describes Enzymes:
Enzyme Inhibition explained:
Short, simple animations about enzymes to show conformational change/strain, transition state (activation energy), proximity and orientation, chemical interaction, biochemical pathway & allosteric enzyme.
Here are some fantastic animated tutorials from McGraw Hill Education – how enzymes work, a biochemical pathway & feedback inhibition of biochemical pathways.
Wiley have a number of Interactive Animations about enzymes, just click on ‘Catalysis’ or ‘Enzyme Inhibition’ or ‘Enzyme Specificity’ in the link.
They also have ‘Introduction to Metabolism’ & click on ‘Metabolic Process Location’ to see an Interactive Animation which is a good review of metabolic processes in the human body.
Topic 5 Evolution & Biodiversity
What is Evolution? – an 8m 53s video from Stated Clearly:
Some excellent interactive animations & tutorials on Variation & Evolution just click on Variation, Selection & Time at the bottom of this page (Learn.Genetics).
In Crash Course Biology #20 – Evolution: It’s a Thing, Hank gets real with us in a discussion of evolution – it’s a thing, not a debate.
Myths and misconceptions about evolution from TED-Ed.
Paul Andersen (from Bozeman High) explains Microevolution.
The Evolution of Life on Earth in 24 hrs – a 2m 19s animation from AsapSCIENCE:
5.1 Evidence for Evolution

Find a video lesson on this sub-topic at Dan Rott videos.
What is the Evidence for Evolution? An 11m video from Stated Clearly:
Proof of evolution that you can find on your body, a 4m video.
Paul Andersen (from Bozeman High) describes pieces of Evidence of Evolution that Charles Darwin used to support the idea of evolution and his process of natural selection (and here is a similar lesson: Evidence for Evolution).
A 2m 30s video on one example of intermediate fossils as evidence for evolution from Richard Dawkins:
5.2 Natural Selection
BioKnowledgy 5.2 natural selection from Chris Paine

Fantastic animated tutorials from McGraw Hill Education – Mechanisms of Evolution (five of them) & a simulation of Genetic Drift.
An excellent narrated tutorial on Evolution – the big picture which includes evidence for evolution (from Sinauer Associates).
In Crash Course Biology #14 – Natural Selection, Hank guides us through the process of natural selection, the key mechanism of evolution. Hank’s brother helps him present The Evolutionary Epic (Big History#5).
Paul Andersen explains Natural Selection, Microevolution and details Examples of Natural Selection.
5.3 Classification of Biodiversity
BioKnowledgy Presentation on 5.3 Classification of biodiversity from Chris Paine
IB Biology 5.3 Slides: Classification & Taxonomy from Jacob Cedarbaum
Find a video lesson on this sub-topic at Dan Rott videos.
Classification of Living Things (4m):
An animated tutorial from McGraw Hill Education on the Three Domains.
In ‘The Classification of Life’, Paul Andersen explains the goal of classification as well as its history (you won’t be tested on this but it’s important) and in The Three Domains of Life he describes the three domains.
In Crash Course Biology #19 – Taxonomy: Life’s Filing System, Hank tells us the background story and explains the importance of the science of classifying living things. In #22 – Simple Animals: Sponges, Jellies & Octopuses, Hank introduces us to the “simplest” of the animals and in #23 – Complex Animals: Annelids & Arthropods, Hank continues our exploration of animal phyla with the more complexly organised annelida and arthropoda.
A quiz on Plant Classification (good luck!).
The importance of classification – woodlice names in the UK & elsewhere.
