Study Notes
Cell Theory
- Three main points of cell theory should be known.
Spontaneous Generation
- Definition of spontaneous generation should be understood.
- Experiments to disprove spontaneous generation, such as Louis Pasteur's swan-neck flask experiment, should be studied.
Cell Research
- Three examples of cell research, with their advancements, implications, and issues, should be known.
Prokaryotes vs. Eukaryotes
- Comparison and contrast of prokaryotes and eukaryotes should be mastered.
Plant Cell Structures
- Organelles unique to plant cells should be identified.
- Reasons for plant cells having certain organelles, like chloroplasts and cell walls.
- What would happen if plant cells did not have chloroplasts.
Animal Cell Structures
- Organelles of an animal cell should be labeled.
Microscopy
- Calculate total magnification of microscopes.
- Measure the size of specimens using magnification and field of view.
- Calculate the missing magnification or original size.
Variables
- Identify controlled, manipulated, and responding variables in experiments (e.g., Louis Pasteur's experiment).
Organelles
- Organelles and their functions (a total of 12). This includes organelles specific to plants.
- Organelles in cells should be understood, as well as their functions.
Cell as an Open System
- Six points related to a cell as an open system should be considered.
