IGCSE Bio Topic 14 – Coordination & Response

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. 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.

An excellent powerpoint that covers it all:

B7.2 TROPIC RESPONSES

We only need to know the first 28 slides:

Tropisms from Marthese Azzopardi

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

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).
