What to Focus On

  • Robert Hooke discovered cells in 1665 by observing cork under a microscope.
  • Leeuwenhoek (1674) discovered free-living cells in pond water using an improved microscope.
  • Robert Brown (1831) discovered the nucleus inside the cell.
  • Unicellular organisms consist of only ONE cell that performs all life functions.
  • Examples of unicellular organisms: Amoeba, Paramecium, Chlamydomonas, bacteria.
  • Multicellular organisms consist of many specialised cells working together.
  • Every cell has three basic components: plasma membrane, nucleus, and cytoplasm.
  • Plant cells additionally have cell wall, large vacuole, and plastids.
  • Protoplasm = cytoplasm + nucleus (the entire living content of a cell).

Common Mistakes to Avoid

All cells have a cell wall — both plant and animal cells.

The cell membrane and cell wall are the same thing.

Osmosis and diffusion are the same process.
