Lesson 6 — Cell Biology Quiz Cheat Sheet
In one line: The twelve facts this quiz keeps testing — organelles, membrane transport, and mitosis.
Fast Recall
1Mitochondria are the primary site of ATP production.
2Eukaryotic ribosomes are 80S; prokaryotic are 70S.
3Chloroplasts are found in plant cells, not animal cells.
4Fluid mosaic model describes the cell membrane.
5Osmosis = water movement across a semipermeable membrane.
6Hypertonic solution → cell shrinks (plasmolysis in plants).
More Fast Recall
7Active transport needs ATP to move against the gradient.
8Anaphase = sister chromatids separate.
9Mitosis produces 2 identical diploid cells.
10Lysosomes digest waste via hydrolytic enzymes.
11Virchow: all cells arise from pre-existing cells.
12Endosymbiosis theory explains why mitochondria have their own DNA.
