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.
