Exploring Key Concepts in Year 9 Biology
Learning objective
Cells: The Building Blocks of Life
Cells are the basic unit of life. Learn about cell structures like the nucleus, mitochondria, and cell membrane.
Photosynthesis: Energy from Light
Photosynthesis is how plants make food using sunlight. The formula is 6CO2 + 6H2O → C6H12O6 + 6O2.
Ecosystems: Interconnected Life
Ecosystems include all living organisms and their environment. Explore food chains and food webs.
Human Digestive System
The digestive system breaks down food for nutrients. Key parts: mouth, stomach, intestines.
Respiration: Energy for Life
Respiration releases energy from glucose. The equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy.
Genetics: Inheritance and Variation
Genetics is the study of heredity. Learn about DNA, genes, and chromosomes.
Adaptation and Evolution
Organisms adapt to their environments over time. Understand natural selection and survival of the fittest.
