Unit+3+Biology

Welcome to Year 12 Biology!

Below is the study design for this unit, it has been modified from the VCAA website. Print a copy of this in your folder so you can check off each topic as we cover it. It will be a useful document when it comes time for the exam.

EXAMS Biology has two exams in Year 12. The mid year exam covers the content from Unit 3 and the end of year exam covers the material from Unit 4. Each exam contributes 33% of your final study score.

SACS There are four SACS in Unit 3. VCAA hand down guidelines as to what you are assessed on for this unit and the topic for each SAC is outlined below.

Outcome 1 – Analyse and evaluate evidence from practical investigations related to biochemical processes 1.1 A written report of a practical activity on the movement of substances across membranes. (25 marks) 1.2 A summary report of a practical activity related to a biochemical process. (25 marks)

Outcome 2 – Describe and explain coordination and regulation of an organism’s immune responses to antigens at the molecular level 2.1 A summary report of a plant or animal stimuli response to chemical and/or physical stimuli. (25 marks) 2.2 A presentation given orally or in annotated poster form on one aspect of the immune response. (25 marks)

The highest mark available for Unit 3 SACs (combined) is 100, therefore each SAC is worth 25 marks. The total score for all four SACs contributes 17% to your final study score.

Area Of Study 1 ﻿Cells are made up of four major biomacromolecules:


 * Carbohydrates (aka. polysaccharides, sugars)


 * Lipids (fats)


 * Proteins (aka. polypeptides)


 * Nucleic Acids
