What to Focus On
- Robert Hooke discovered cells in cork in 1665.
- Anton Van Leeuwenhoek observed living cells and named them 'animalcules'.
- Schleiden and Schwann proposed the cell theory in 1839.
- Prokaryotes lack a nucleus and membrane-bound organelles.
- Eukaryotes have a nucleus and organelles.
- Prokaryotes have 70S ribosomes; eukaryotes have 80S.
- Plant cells have a cell wall; animal cells do not.
- Plant cells have chloroplasts; animal cells lack them.
- Plant cells have large vacuoles; animal cells have small ones.
Common Mistakes to Avoid
Viruses are considered living cells because they can reproduce.
All cells have a nucleus, so prokaryotes must have a small nucleus.
Cell wall and cell membrane are the same thing; one is just the stronger version of the other.
Memory Tips
Cell Theory: All organisms are made of cells; cells are the basic unit of life; all cells come from pre-existing cells.
