Biology 2.1.7: Prokaryotic Cells Flashcards
1
Q
how are prokaryotic cells and eukaryotic cells similar?
A
they both have: a plasma membrane, cytoplasm, ribosomes, DNA + RNA
2
Q
how are prokaryotic cells different from eukaryotic cells?
A
they; are smaller, no nucleus, no membrane bound organelles, wall is made of peptidoglycan, have naked DNA the floats free as a loop
3
Q
what are some other features of a prokaryotic cells?
A
protective waxy capsule surrounding their cell wall, small loops of DNA (plasmids), flagella, pili
4
Q
what is flagella?
A
long whip-like projections which enable them to move
5
Q
what is pili?
A
small hair-like projections that enable bacteria to adhere to host cells
6
Q
how do prokaryotic cells divide?
A
through binary fission due to not having linear chromosomes
