Biology, Grade 11, University Preparation (SBI3U)




This course furthers students’ understanding of the processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biodiversity; evolution; genetic processes; the structure and function of animals; and the anatomy, growth, and function of plants. The course focuses on the theoretical aspects of the topics under study, and helps students refine skills related to scientific investigation.

Prerequisite : SNC2D

Grade : 11

Credit value : 1

Unit One

Scientific Investigation Skills and Career Exploration

  • Demonstrate scientific investigation skills (related to both inquiry and research) in the four areas of skills (initiating and planning, performing and recording, analysing and interpreting, and communicating)
  • Identify and describe a variety of careers related to the fields of science under study, and identify scientists, including Canadians, who have made contributions to those fields

Unit Two

Diversity of Living Things

  • Evaluate the importance of medical and other technological developments related to systems biology, and analyse their societal and ethical implications
  • Investigate cell division, cell specialization, organs, and systems in animals and plants, using research and inquiry skills, including various laboratory techniques
  • Demonstrate an understanding of the hierarchical organization of cells, from tissues, to organs, to systems in animals and plants

Unit Three


  • Analyse the economic and environmental advantages and disadvantages of an artificial selection technology, and evaluate the impact of environmental changes on natural selection and endangered species
  • Investigate evolutionary processes, and analyse scientific evidence that supports the theory of evolution
  • Demonstrate an understanding of the theory of evolution, the evidence that supports it, and some of the mechanisms by which it occurs

Unit Four

Genetic Processes

  • Evaluate the importance of some recent contributions to our knowledge of genetic processes, and analyse social and ethical implications of genetic and genomic research
  • Investigate genetic processes, including those that occur during meiosis, and analyse data to solve basic genetics problems involving monohybrid and dihybrid crosses
  • Demonstrate an understanding of concepts, processes, and technologies related to the transmission of hereditary characteristics.

Unit Five

Physics: Light and Geometric Optics

  • Analyse the relationships between changing societal needs, technological advances, and our understanding of internal systems of humans
  • Investigate, through laboratory inquiry or computer simulation, the functional responses of the respiratory and circulatory systems of animals, and the relationships between their respiratory, circulatory, and digestive systems
  • Demonstrate an understanding of animal anatomy and physiology, and describe disorders of the respiratory, circulatory, and digestive systems.

Unit Six

Plants: Anatomy, Growth, and Function

  • Evaluate the importance of sustainable use of plants to Canadian society and other cultures
  • Investigate the structures and functions of plant tissues, and factors affecting plant growth
  • Demonstrate an understanding of the diversity of vascular plants, including their structures, internal transport systems, and their role in maintaining biodiversity
