IGCSE Bio Topic 6 – Plant Nutrition

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.

A introductory lesson in transport systems from Ms Cooper (7m).

Transport in plants from Ruba Din

8.1 TRANSPORT IN PLANTS & 8.2 WATER UPTAKE

Lessons from Ms Cooper: Transport of water through the root (10m 10s); Transport of water in stem (5m 20s); Movement of water through the leaf (7m 24s).

Transport in plants in three and a half minutes:

Or how about a whole lesson from Mr Paul Andersen? He goes into more detail than we need (we have to know about Dicots but not Monocots), but he’s good:

The most amazing thing about trees (5m video).

8.3 TRANSPIRATION

More-detailed than we need but it’s good:

Mr Paul Andersen starts by defining transpiration as evaporation of water from a leaf. He then describes how a potometer can be used to measure the rate of transpiration in different environments:

Lessons from Ms Cooper: Transpiration (15m) and Plant Transport Experiments from Ms Cooper (8m 42s).

How to use set-up a potometer: Transpiration: the power of the potometer, a 17m video from STEM Learning.

8.4 TRANSLOCATION

Here’s a 2m video on Phloem Loading (in a little more detail than we need).

A lesson in Translocation from Ms Cooper (10m 10s).

14.5 Tropic Responses

Tropisms from Marthese Azzopardi

Science Bank 15: Part 3 covers Plant Tropisms (from 9m 25s to 14m 30s):

14.5 Tropic responses notes in downloadable word format.

 

A 3 minute introduction to tropisms (from Twig World).

Plant Control – Paul Andersen explains how plants use hormones to respond to their environment. We only need to know about auxins (to 3m 40s).

CIRCULATION & BLOOD VESSELS:

GCSE Bitesize – Blood Circulation covers how the heart circulates blood & the composition of blood (6m 35s).

Other videos include The Virtual Body – Circulation, Respiration & Breathing (19m), Science in Focus – Life Blood (19m 15s) & BBC Short Circuit Blood & Circulation (19m).

Various animations about heart & circulation problems can be found here.

BLOOD:

Blood GCSE from dhmcmillan

Blood video (a 3m 44s lesson) & Blood music video by Peter Weatherall – 3m 3s and very catchy! And here is a day in the life of a Red Blood Cell (a one minute cartoon) & here a white blood cell chases a bacterium (20s).

2.9 Photosynthesis

A good, general overview of Photosynthesis (2m 47s):

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

PRACTICAL – Rate of Photosynthesis

Here are two from BiologyCorner: Photosynthesis Virtual Lab and Algal beads and Photosynthesis.

Dynamics of Photosynthesis – a lab simulation and from Gizmos – Photosynthesis Lab.

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:
