SBI3C

Course: Biology, Grade 11, College Preparation (SBI3C)

Strand C: Microbiology

​

Big Ideas:

• Groups of microorganisms have common characteristics, and these characteristics enable them to interact with other organisms in the environment

• Microorganisms can have both positive and negative effects on the environment.

• The technological use of microorganisms raises many ethical issues.

 

Overall Expectations:

• C1. assess the effects of microorganisms in the environment, and analyse ethical issues related to their use in biotechnology

• C2. investigate the development and physical characteristics of microorganisms, using appropriate laboratory equipment and   techniques;

• C3. demonstrate an understanding of the diversity of microorganisms and the relationships that exist between them.

 

Specific Expectations:

C1. Relating Science to Technology, Society, and the Environment 

By the end of this course, students will:

• C1.1 assess some of the effects, both beneficial and harmful, of microorganisms in the environment (e.g., decomposers break
   down waste, E. coli in water systems poses a severe risk to human health) [AI, C]

• C1.2 analyse ethical issues related to the use of microorganisms in biotechnology (e.g., with respect to the use of bacterial

         insecticides, the patenting of modified microorganisms) [AI, C]

C2. Developing Skills of Investigation and Communication

By the end of this course, students will:

• C2.1use appropriate terminology related to microbiology, including, but not limited to: fission, conjugation, phage, dormancy,

        morphology, mycelium, spore, pathogen, and plasmid [C]

• C2.2 compare and contrast the cell structures of eukaryotes such as fungi, protozoa, and algae [PR, AI]

• C2.3 prepare a laboratory culture of microorganisms (e.g., acidophilus) on agar, using proper aseptic techniques [PR]

• C2.4 investigate the effect of antibacterial agents on different bacterial cultures (e.g., the effects of antibacterial soap or mouthwash on a bacterial culture) [PR]

• C2.5 investigate and analyse the conditions (e.g., optimal temperature) needed by microorganisms for growth [PR, AI]

​

C3. Understanding Basic Concepts

By the end of this course, students will:

• C3.1 describe the anatomy and morphology of various groups of microorganisms (e.g., eukaryotes, prokaryotes, viruses)

• C3.2 explain the differences between the life cycles of eukaryotic and prokaryotic microorganisms in terms of cell division

• C3.3 explain the vital roles of microorganisms in symbiotic relationships with other organisms (e.g., gut bacteria in cows digest  cellulose; mycorrhizal fungi penetrate and effectively extend a plant’s root system)

• C3.4 explain the different methods of reproduction in various types of bacteria, viruses, and fungi

• C3.5 describe how different viruses, bacteria, and fungi can affect host organisms, and how those effects are normally treated or prevented (e.g., hepatitis viruses can damage the liver, but vaccinations can prevent infections; streptococcus bacteria can

        cause respiratory infections, which are treated with antibiotics; ringworm is a fungal infection of the skin, treated with
        fungicides)
