Q

What are the differences between prokaryotic cells and eukaryotic cells

A
  • Prokaryotic cells do not have membrane bound organelles
  • prokaryotic cells are much smaller than Eukaryotic cells (-100)
  • Both have ribosomes but prokaryotic cells have 70s ribosomes and eukaryotic have 80s ribosomes

Q

Prokaryotic cells functions
nucleoid
Plasmids
70s ribosomes
Capsule
Cell wall
Plasma membrane
Flagellum
Cytoplasm

A

-Nucleoid holds the DNA
-Plasmids are small loops of DNA that stores extra genetic information
-70s ribosomes are used for protein synthesis
-Capsules are the protective layer used for attachment site for exchange
-Cell wall is used for rigidity
-Plasma membrane controls what goes in and out of the cell
-flagellum assist the cell in movement
-Cytoplasm is where all the chemical reactions take place
