A2.1.3—Spontaneous origin of cells Topic Practice
Practise outlining stages proposed for cell origins, including organic molecule synthesis, polymers, self-replication and membrane-bound protobionts.
How this is tested
- describe sequences from simple organic molecules to polymers and membranes
- explain how protobionts could maintain an internal chemistry unlike surroundings
- identify early cell features such as plasma membranes before later organelles
