Biology — A-Level
Five chapters — from the study of life through reproduction and genetic continuity.
Chapter 1
Introduction to Biology
What biology studies, the characteristics that define living things, and the scientific method biologists use to investigate them.
Chapter 2
Cell Structure and Organization
Explore what animal and plant cells are built from, how microscopes reveal them, and how specialized cells build up into tissues, organs, and organ systems.
Chapter 3
Support and Locomotion
The human skeleton, joints and muscles that provide support and movement, and how plants support themselves without a skeleton.
Chapter 4
Body Systems to Sustain Life
The digestive, respiratory, circulatory, excretory, nervous and endocrine systems, and how they work together to maintain homeostasis.
Chapter 5
Continuation of Life
How organisms reproduce, divide their cells, and pass genetic information on to the next generation.
