Intermediate 2 Biology

The Intermediate 2 Biology course has 3 units which will build on the knowledge and skills learned in Standard Grade Biology. To gain entry to this course your prelim results should predict that you will gain:
Standard Grade Biology – Grade 3 or 4 for both Knowledge & Understanding and
Problem Solving

Standard Grade Chemistry or Physics – Grade 1 or 2 for both Knowledge &
Understanding and Problem Solving

The 3 units taught are:

Unit 1 – Living Cells

(a) Structure and function of a variety of cells
(b) Diffusion and osmosis in plant and animal cells
(c) Enzyme action


(d) Aerobic and anaerobic respiration
(e) Photosynthesis

Unit 2 – Environmental Biology & Genetics

(a) Ecosystems
(b) Factors affecting variety in a species


(c) Genetics
(d) Natural selection
(e) Selective breeding & genetic engineering

Unit 3 – Animal Physiology

(a) Mammalian nutrition
(b) Control of the internal environment
(c) Circulation and gas exchange
(d) Sensory mechanisms and processing of information


Homework will be given on a regular basis: reading over and learning the work covered in class together with questions to consolidate the information that you have learned.


At the end of each unit, the following assessments will be given:

- end of unit prelim (questions at a similar level to those of the final exam)
- end of unit assessment *
- practical assessment*

*both of these elements must be “passed” before an award will be given in the final exam.

The prelim in February will test Living Cells and Environmental Biology & Genetics
