Prokaryote cells working together

Question 1

What are prokaryotes?

Answer 1

Single celled organisms which do not have membrane bound organelles

Question 2

Features of a prokaryote cell in ALL prokaryote cells

Answer 2

Cell membrane
Cell wall
Cytoplasm
Ribosomes
circular loop of DNA

Question 3

Additional features of prokaryotes in SOME prokaryote cells

Answer 3

Pilli
Flagellum
Slime capsule
Plasmids

Question 4

What is cell wall made up of in prokaryotes?

Answer 4

Meurin a glycoprotein

Question 5

Eukaryote cell membranes vs prokaryote cell membranes

Answer 5

Eukaryotes have cholesterol in membranes which prokaryotes DO NOT

Question 6

Ribosomes in a prokaryote cell

Answer 6

70s

Question 7

Circular loop of DNA in a prokaryote

Answer 7

DNA floats free in the cytoplasm and not membrane bound
A loop with no ends
Not bound to histone proteins

Question 8

Flagellum

Answer 8

What some prokaryotes have to help them move

Question 9

Plasmids

Answer 9

What some prokaryotes have which are small loops of DNA which can encode for antibiotic resistance

Question 10

Slime capsule

Answer 10

Secreted slime encoded for by ribosomes to protect this bacteria from immune system cells

Question 11

How do prokaryote cells divide?

Answer 11

Binary fission

Question 12

Stages of binary fission

Answer 12

Plasmids and circular loop of DNA is replicated
Cell gets bigger and the copies of DNA will move to opposite ends of cell
CYTOPLASM begins to divide
= 2 identical copies of bacteria

Question 13

Binary fission involving plasmids

Answer 13

Plasmids can replicate multiple times
So daughter cells may have variable numbers of copies of plasmids
