A2 Biology Communication, Homeostasis and Energy (OCR F214)

A comprehensive revision guide made using the OCR syllabus so that absoultely everything is covered. Quite detailed so not ideal if your after quick notes, but theyre more condensed than a text book. Some extra detial to help answer the "suggest why" questions we all know and hate. Hope these can come in useful :)

Communication and Homeostasis
Communication
1 ©Ross Edwards 2013
Different cells perform different functions, so communication systems ensure that these cells
can work together
Cell signalling
The hormonal system transports hormones through the blood, enabling long term responses to
be coordinated
Homeostasis
Multicellular organisms require communication systems…

These notes are brilliantly presented with good annotated diagrams covering the topics included in the OCR F214 module. This includes communication, homeostasis, nerves, hormones, respiration and photosynthesis. Use them as your notes or to create revision cards of the key facts.
