Key Questions:

1. What is the basic structure of plant and animal (eukaryotic) cells?
   • Plant and animal Cells (eukaryotic Cells) have a Cell membrane, cytoplasm and genetic material enclosed in a nucleus.
2. What is the structure of a bacterial cell?
   • Bacteria have cytoplasm and a Cell membrane surrounded by a Cell wall.
3. What is the order of magnitude of an ant, DNA, red blood cell, carbon atom and bacterial cell?
   • The order of magnitude of an ant, DNA, red blood Cell, carbon atom and bacterial Cell is as follows: ant > red blood Cell > bacterium > DNA > carbon atom.
4. Are bacterial (prokaryotic) cells bigger or smaller than eukaryotic cells?
   • Bacterial Cells (prokaryotic Cells) are much smaller in comparison to eukaryotic Cells.
5. What is unique about the DNA in a bacterial cell?
   • In bacteria the genetic material is not enclosed in a nucleus. It is a single DNA loop and there may be one or more small rings of DNA called plasmids.
