O Level Biology (Ordinary Level)

Overview:

O Level Biology introduces students to the fundamental life processes and structures of living organisms. It emphasizes observation, basic lab skills, and general biological knowledge.

Key Topics:

 Cell Biology: Cell structure, function, differences between plant and animal cells

 Classification: Five kingdoms, vertebrates, invertebrates

 Movement in and out of Cells: Diffusion, osmosis, active transport

 Biological Molecules: Carbohydrates, proteins, lipids, enzymes

 Plant Biology: Photosynthesis, transpiration, plant nutrition, transport

 Human Biology: Digestive, circulatory, respiratory, nervous, and excretory systems

 Reproduction: Sexual and asexual reproduction in plants and humans

 Inheritance: Basic genetics, dominant/recessive traits, Punnett squares

 Ecology: Food chains/webs, energy flow, populations, human impact

 Health and Disease: Pathogens, immunity, and healthrelated issues

Skills Developed:

 Labeling and drawing biological diagrams

 Interpreting data from charts and graphs

 Conducting basic experiments

 Using scientific vocabulary appropriately

Objective:

To build a solid biological foundation and promote curiosity about living organisms and life processes.
