Cambridge International AS and A Level Biology <strong>9700</strong> <strong>sy</strong>llabus Introduction<br />

Why Cambridge International AS and A Level Biology?<br />

Universities value learners who have a thorough understanding of key concepts in biology, an<br />

in-depth knowledge of biology’s most important themes and strong practical skills. Cambridge<br />

International AS and A Level Biology helps learners develop the knowledge and skills that will<br />

prepare them for successful university study.<br />

Our learners also develop lifelong skills of scientific enquiry, confidence in technology, and<br />

communication and teamwork skills.<br />

Key concepts<br />

The key concepts on which this <strong>sy</strong>llabus is built are set out below. These key concepts can help teachers<br />

think about how to approach each <strong>sy</strong>llabus topic in order to encourage learners to make links between<br />

topics and develop a deep overall understanding of the subject. The teaching support package gives<br />

teachers guidance on integrating the key concepts into their teaching. See page 8 for more information on<br />

our teacher support.<br />

As a teacher, you will refer to these concepts again and again to help unify the subject and make sense of<br />

it. If mastered, learners can use the concepts to solve problems or to understand unfamiliar subject-related<br />

material.<br />

• Cells as the units of life<br />

A cell is the basic unit of life and all organisms are composed of one or more cells. There are two<br />

fundamental types of cell: prokaryotic and eukaryotic.<br />

• Biochemical processes<br />

Cells are dynamic: biochemistry and molecular biology help to explain how and why cells function as<br />

they do.<br />

• DNA, the molecule of heredity<br />

Cells contain the molecule of heredity, DNA. Heredity is based on the inheritance of genes.<br />

• Natural selection<br />

Natural selection is the major mechanism to explain the theory of evolution.<br />

• Organisms in their environment<br />

All organisms interact with their biotic and abiotic environment.<br />

• Observation and experiment<br />

The different fields of biology are intertwined and cannot be studied in isolation: observation and<br />

enquiry, experimentation and fieldwork are fundamental to biology.<br />

Guided learning hours<br />

Guided learning hours give an indication of the amount of contact time teachers need to have with learners<br />

to deliver a particular course. Our <strong>sy</strong>llabuses are designed around 180 guided learning hours for Cambridge<br />

International AS Level, and around 360 guided learning hours for Cambridge International A Level.<br />

These figures are for guidance only. The number of hours needed to gain the qualification may vary<br />

depending on local practice and the learners’ previous experience of the subject.<br />

Prior learning<br />

We recommend that candidates who are beginning this course should have previously completed a<br />

Cambridge O Level or Cambridge IGCSE course, or the equivalent, in Biology or in Co-ordinated Science.<br />
