What are the two types of cells? - ANSWER● Eukaryotic (plant and animal)
● Prokaryotic (bacteria)
What are the differences between eukaryotic and prokaryotic cells? - ANSWERProkaryotic cells are
much smaller than eukaryotic cells.
Eukaryotic cells contain membrane bound-organelles and a nucleus containing genetic material, while
prokaryotes do not.
How is genetic information stored in a prokaryotic cell? - ANSWERFound free within the cytoplasm as:
● Chromosomal DNA (single large loop of circular DNA)
● Plasmid DNA
What are plasmids? - ANSWER● Small, circular loops of DNA found free in the cytoplasm and separate
from the main DNA.
● Carry genes that provide genetic advantages e.g. antibiotic resistance.
List the components of both plant and animal cells (5) - ANSWER● Nucleus
● Cytoplasm
● Cell membrane
● Mitochondria
● Ribosomes

List the additional cell components found in plant cells (3) - ANSWER● Chloroplasts
● Permanent vacuole
