Prokaryotic cell structures

Question 1

prokaryotic cell is

Answer 1

a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.

Question 2

plasma membrane

Answer 2

a semi-permeable barrier that separates the cell’s interior from its surrounding environment

Question 3

Protein associated with the plasma membrane

Answer 3

receptor, enzyme, transporter, ion channel

Question 4

Do prokaryotic cells contain cholestorol?

Answer 4

No

Question 5

Ribosomes-

Answer 5

links amino acids together to make protein

Question 6

cytosol

Answer 6

the gel-like fluid contained in cytoplasm

Question 7

cytoplasm in a prokaryotic cell….

Answer 7

Fills the whole Space bounded by the cell membrane

Question 8

flagella (singular: flagellum) in prokaryotic cell (6 characteristics)

Answer 8

outside cell wall

made of chains of a protein called flagellin

attached to protein hook

anchored to wall and membrane by the basal body

primary function is motility

Has different structure in Gram positive and Gram negative bacteria

Question 9

pili

Answer 9

tubular outgrowths helpful in attaching to recipient cell/assist in DNA transfer

Question 10

Fimbriae

Answer 10

function to attach the cells to surfaces.

Question 11

provides rigidity and structure

Peptidoglycan

Gram pos

Gram neg

Question 12

Peptidoglycan

Answer 12

1. Sugar and protein matrix that makes up the cell wall
2. Often a target of antibiotics.

Question 13

gram positive has

Answer 13

plasma membrane and thick cell wall

Question 14

gram neg has

Answer 14

thin cell wall between two membranes
