Read about the new exam layout at the bottom of this article and check out the videos below!

1. Enzyme video: Enzymes appear in nearly every Biology Leaving Certificate paper. This video looks at key terms that are related to enzymes – Biological catalyst, pH, temperature, substrate, product, specific, optimum and denatured.

2. Cell Division video: Cell division appears quite regularly on the Leaving Certificate Biology paper. This video looks at the Interphase and the events of mitosis.

4. Heart video: This video looks at the structure of the heart and how blood flows through the pulmonary and systemic circuit.

5. Ecology video (Food chains, food webs and pyramid of numbers): Ecology is usually worth between 15% and 25% of the paper. This video looks at one of the ecology sections - food chains, food webs and pyramid of numbers.

6. Structure of a Flowering plant: This video looks at the structure of a leaf and the differences between a monocotyledon and dicotyledon stem.
