Laboratory Safety and Apparatus
Before we explore biology, we must know how to work safely and correctly in the laboratory. This module introduces essential safety rules, common biological apparatus, and the practical skills expected in the ZIMSEC practical exam.
- 1.1Laboratory Rules and Safety SymbolsIncluded
- 1.2Common Laboratory Apparatus and Their UsesIncluded
- 1.3Using the Light MicroscopeIncluded
Cells and Levels of Organisation
The cell is the fundamental unit of life. In this module, students study the structure of plant and animal cells, the functions of organelles, and how cells are organised into tissues, organs, and organ systems.
- 2.1Structure of Plant and Animal CellsIncluded
- 2.2Cell Processes: Diffusion, Osmosis, and Active TransportIncluded
- 2.3Levels of OrganisationIncluded
Nutrition
This module covers the nutritional needs of both plants and animals. Students explore photosynthesis, the human digestive system, food tests, and the importance of a balanced diet.
- 3.1PhotosynthesisIncluded
- 3.2Food Tests and NutrientsIncluded
- 3.3Human DigestionIncluded
Respiratory Systems
Students explore how living organisms obtain energy through aerobic and anaerobic respiration, the structure of the human respiratory system, and gas exchange in different organisms.
- 4.1Aerobic and Anaerobic RespirationIncluded
- 4.2The Human Respiratory SystemIncluded
- 4.3Gas Exchange in Other OrganismsIncluded
Transport Systems
This module investigates how substances are transported through the bodies of humans and plants. Topics include the composition of blood, the heart, blood vessels, lymphatic system, and transport in plants.
- 5.1The Human Heart and Blood VesselsIncluded
- 5.2Blood and the Lymphatic SystemIncluded
- 5.3Transport in PlantsIncluded
Reproductive Systems
Students examine the reproductive systems of humans and flowering plants, covering the processes of fertilisation, development, and the factors influencing reproduction.
- 6.1Human Reproductive SystemIncluded
- 6.2Fertilisation, Pregnancy, and BirthIncluded
- 6.3Reproduction in Flowering PlantsIncluded
Health and Diseases
The final module explores how diseases affect the human body, how they are transmitted and prevented, and how the immune system and modern medicine protect us.
- 7.1Types of Diseases and Their CausesIncluded
- 7.2The Body's Defence MechanismsIncluded
- 7.3Prevention, Control, and Treatment of DiseaseIncluded
