From the Stage 2 SACE Biology course outline, this video discusses:
- The cell theory unifies all living things.
- The cell membrane separates the cell cytoplasm from its surroundings and controls the exchange of materials, including nutrients and wastes, between the cell and its environment.
• Describe and represent the fluid mosaic model of the cell membrane.
- The major types of cells are
– prokaryotic
– eukaryotic.
- Prokaryotic and eukaryotic cells have many features in common, which is a reflection of their common evolutionary past.
• Compare prokaryotic and eukaryotic cells with respect to their:
– size
– internal organisation
– shape and location of chromosomes.
- Prokaryotes only exist as single cells.
