What is the main distinction between prokaryotic and eukaryotic cells?
- Eukaryotic cells have DNA in the nucleus, while prokaryotic cells have DNA in the cytoplasm. (correct)
- Prokaryotic cells possess ribosomes, while eukaryotic cells lack them.
- Prokaryotic cells have a nucleus, while eukaryotic cells do not.
- Eukaryotic cells contain DNA in the cytoplasm, while prokaryotic cells contain DNA in the nucleus.

Study Notes
Prokaryotic Cells
- Possess a cell wall
- Contain plasmids, small circular DNA molecules
- Lack a nucleus, DNA is located in the cytoplasm
- Possess ribosomes, responsible for protein synthesis
Eukaryotic Cells
- Contain a nucleus where DNA is stored
- Possess a cell membrane that regulates what enters and exits the cell
Microscopy
- Magnification refers to how much larger an object appears under a microscope.
- Resolution determines the ability to distinguish between two closely spaced objects.
- Light microscopes use visible light, offering lower magnification and resolution compared to electron microscopes.
- Electron microscopes provide higher magnification and resolution, allowing visualization of smaller structures.
- Specimens for light microscopy can be alive, while electron microscopy requires specimens to be dead and prepared.
Scientific Drawings
- Do not use shading.
- Avoid crossing labeling lines.
- Label lines should converge towards a central point.
- Use pencil for labeling.
- Only draw essential features.
- Specify magnification.
