Ecology: The study of living organisms and their environment. The study of ecology aims to explain why organisms live where they do. To do this ecologists study ecosystems, areas that can vary in size from a pond to the whole planet.
Ecosystem: A reasonably self-contained area together with all its living organisms.
Endodermis: in plants, the outer layer of the vascular bundle. Vitally, it contains the Casparian strip which regulates transport of ions into the vascular bundles of roots. Endodermis means ‘inner skin’
Epidermis: In plants, the outer layer of root. Root hair cells are epidermal cells adapted to increase the surface area for absorption. Epidermis means ‘outer skin’

Fertilisers (artificial / organic): Materials added to the soil which increase nutrient availability for plants.
As I write the biology dictionary and make the videos to help you learn the definitions by listening in addition to reading them, you'll get the added benefit of hearing and learning the correct pronunciation of biological terminology - but there's more! I'm also making some interactive revision flashcards too! So you can revisit the key words when revising and really embed those a level biology definitions in your head! - The flashcards will be like this (See image below and click to download).

A-Level Biology is a whole lot easier when you know the definitions of commonly used words. This biology dictionary is here to help you learn those A level biology definitions. Remember, a good command of biological terminology (at GCSE but especially at A level) can mean the difference between a poor grade and an excellent one! Since of course you get marks awarded for using the correct biological definitions in the right context when answering exam questions and writing up lab work, coursework and assignments.
The biology dictionary is mainly aimed at a level biology students since at a level, the amount of new technical language expect is quite a lot!
Make learning biology definitions a regular part of your studies and keep checking in as more keywords and gcse biology definitions and a level biology definitions are added.
