cell structure (prokaryotic cells)

Question 1

what is an example of a prokaryotic cell?

Answer 1

bacteria

Question 2

what is the structure of the plasma membrane?

Answer 2

made from lipids and proteins

Question 3

what is the structure of the cell wall?

Answer 3

made of murein- a glycoprotein

Question 4

what is the role of a capsule?

Answer 4

made of secreted slime, helps to protect bacteria from attack by immune system cells

Question 5

what are plasmids?

Answer 5

small loops of DNA, can be passed between prokaryotes

Question 6

how is DNA found in prokaryotic cells?

Answer 6

doesn’t have a nucleus- free floating in the cytoplasm, contains circular DNA which is free floating

Question 7

what is a flagellum?

Answer 7

long, hair like structure that rotates to make a prokaryotic cell move

Question 8

what does the cytoplasm contain?

Answer 8

does not contain membrane bound organelles, only ribosomes

Question 9

how do prokaryotic cells replicate?

Answer 9

by binary fission

Question 10

how does binary fission occur?

Answer 10

circular DNA and plasmids replicate
main DNA loop replicated once but plasmids replicated many times
cell gets bigger and DNA loops move to opposite poles
cytoplasm begins to divide
cytoplasm divides and 2 daughter cells are produced
