Study Notes
Unit 1: Laboratory General Procedures, Safety, Emergency Procedures and Biology Lab Equipment
-
Lab Equipment Identification: Use the letters provided to identify lab equipment. Example: Beaker (A), Flask (B), etc.
-
Safety Procedures: Always know the location and use of safety equipment (safety shower, eyewash, fire extinguisher).
-
Sharp Instruments: Direct sharp instruments away from yourself and others.
-
Lab Injuries: If injured, apply pressure to the cut immediately and get medical attention, whether the cut is severe or not. Report all accidents, breakages, and procedural errors to a teacher immediately.
-
Waste Disposal: Dispose of used matches in a water-filled container.
Unit 2: The Science and Chemistry of Life
-
Relative Acidity: A pH 2 solution is 100 times more acidic than a pH 0 solution.
-
Biological Hierarchy: List the following in increasing order: molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem.
-
Properties of Life: All organisms reproduce, maintain constant internal temperature, and respond to stimuli.
-
Control Groups: In experiments, control groups provide a baseline for comparison with the experimental group..
-
Common Biological Elements: The four most common elements in living organisms are carbon, hydrogen, nitrogen, and oxygen.
-
Atomic Particles: Subatomic particles located inside the atomic nucleus are protons and neutrons.
-
Subatomic particles located outside the atomic nucleus include electrons.*
-
Chemical Bonds: Electrons are involved in chemical bonding.
-
Types of Chemical Bonds: Covalent bonds use electron sharing, ionic bonds use electron transfer.
Unit 3: Biochemistry
-
Macromolecules: Label the macromolecules: carbohydrates, lipids, nucleic acids, and proteins.
-
Polymer Synthesis: Polymers are built through dehydration synthesis (removing water).
-
Bonding: Atoms bond to become more stable.
-
Carbohydrates: Monomer is a monosaccharide.
-
Nucleic Acids: Monomer is a nucleotide.
-
Lipids: Do not contain nucleotides.
-
Proteins: Monomer is an amino acid.
Unit 4: Cell Structure, Cell Function, and the Microscope
-
Cell Types: Bacteria are prokaryotic, while plants and animal cells are eukaryotic. Eukaryotic cells contain membrane-bound organelles.
-
Cell parts: The nucleus, Golgi apparatus, and ribosomes are components of the cell.
-
Microscope Parts: Describe the function of the microscope parts like ocular lens, illuminator, stage clips, etc.
-
Microscope Adjustments: The fine adjustment knob is used with high-power objective lenses.
-
Microscopes: The scanning objective lens has the greatest viewing angle.
-
Cellular Functions: Mitochondria carry out cell respiration, and chloroplasts participate in photosynthesis.
Unit 5: Homeostasis and Cell Transport
-
Plasma Membrane: The plasma membrane is selectively permeable.
-
Solutions:
- Hypertonic solution: causes cells to shrivel.
- Hypotonic solution: causes cells to swell.
- Isotonic solution: maintains cell shape as the concentration of dissolved substances in the solution is equal to the concentration inside the cell.
-
Transport Types: passive transport (no energy required, moves from high to low concentration), and active transport (requires energy, moves from low to high concentration).
Unit 6 and 7: Photosynthesis and Cellular Respiration
-
Photosynthesis Location: Photosynthesis occurs in chloroplasts.
-
Photosynthesis Process: Includes the light reaction, and the Calvin cycle (inputs needed are carbon dioxide and water to produce glucose and oxygen).
-
**Respiration:**Cellular Respiration occurs in the mitochondria.
-
Fermentation: A metabolic process that occurs in the absence of oxygen (example: lactic acid fermentation).
Unit 8 and 9: Cell Reproduction and Modern Genetics
-
Cell division: Mitosis produces identical cells; meiosis produces genetically different cells.
-
Mitosis Process: Includes interphase, prophase, metaphase, anaphase, and telophase.
-
Meiosis: Results in the production of gametes (sex cells).
-
Genetics: Use Punnett squares for predicting genetic outcomes, and determining genotypes and phenotypes.
-
Cell Cycle: Most of a eukaryotic cell's time is spent in interphase.
-
Characteristics: Observable characteristics of a trait/organism (e.g.: observable physical features such as height or eye colour) are called the phenotype. Their genetic makeup, or the combination of alleles an organism possesses, is called the genotype.
-
Modern Genetics Concepts: Discuss terms and concepts in modern genetics.
