Cell Biology and Biotechnology in one look

the cell's parts and their jobs, and the techniques that now edit what a cell does

The cell, and the two great divisions

  • the cell theory: all living things are made of cells, the cell is the basic unit of life, and every cell arises from a pre-existing cell
  • a prokaryotic cell has no true nucleus and no membrane bound organelles. Bacteria are the example
  • a eukaryotic cell has a true nucleus enclosed in a membrane, and organelles each with their own membrane
  • the nucleus holds the DNA and directs everything the cell does
  • plant and animal cells are both eukaryotic, differing in a few parts rather than in kind
  • the cell membrane is selectively permeable, letting some substances through and holding others back

How CapCompass uses this sheet

These notes are not a standalone PDF. CapCompass plans Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Cell Biology and Biotechnology the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
