Biology

From ZuluNotes - Free Leaving Cert Notes

The new syllabus, first examined in 2004, is composed of science for the enquiring mind or pure science, which constitutes approximately 70% of the syllabus, and the technological, political, social and economic aspects of biology, which constitutes the remaining 30%. The syllabus consists of three units:

• Unit One: Biology - The Study of Life
• Unit Two: The Cell
• Unit Three: The Organism

Contents 1 Higher/Ordinary 2 Paper 3 Contents 3.1 The Study Of Life 3.2 The Cell 3.3 The Organism

Higher/Ordinary

Ordinary level and Higher level are differentiated on the basis of:

1. Range of topics: The Higher level incorporates the Ordinary level. At Higher level an extended range of topics is required.
2. Depth of treatment: The Ordinary level course provides an overview of biology and its application to everyday life. At Higher level a deeper and more quantitative treatment of biology is required.

Paper

Time : 3 hours

Section A Answer any five questions from this section. Each question carries 20 marks. This is the short question section.

Section B Answer any two questions from this section. Each question carries 30 marks. These questions are longer, and broken into two parts. Part (a), usually a definition or other short question, carries 6 marks and part (b), which usually entails a longer description, such as that of an experiment, carries 24 marks in each question in this section.

Section C Answer any four questions from this section. Each question carries 60 marks.

You should spend not more than 30 minutes on Section A and 30 minutes on Section B, leaving 120 minutes for Section C

Pacing:

• Section A - should do all 6 questions. Spend 4 mins on each.
• Section B - 2 mins to decide which two to do. 13 mins per question.
• Section C - 3 mins to decide which four to do. 26 mins per question.
• Check answers - 21 mins
