Bacterial Structure of Prokaryotes

Question 0

Define Cytosol

Answer 0

Mixture of water & solutes.

Question 1

Define Cytoplasm

Answer 1

Fluid environment inside the cell
Cytosol
maintains temperature
allows for chemical interactions to take place
(example full swimming pool vs empty)

Question 2

What are plasma membranes

Answer 2

Physical boundary of the cells & controls interaction w/ the enviroment
protective & selective
(example water ballon)

Question 3

What is the Nucleoid?

Answer 3

Region where the DNA is located
Chromosome
DNA

Question 4

What are Ribosomes

Answer 4

Protein production site
non membrane bound organelle
common to both Eukaryotes & Prokaryotes

Question 5

What are Inclusion Bodies?

Answer 5

Storage sites

Question 6

What is a cell wall?

Answer 6

Vary in density from species to species
composed of peptido glycan (complex of proteins & sugars)
protection from external damage & explosion
prevents from over filling w/ water

Question 7

Outer/External Membrane

Answer 7

Primarily used for attaching to surfaces
contains a macromolecule called lipopollysacharide. (Lipids&Sugars)
Main focus is attatchment
secondary function is to send our immune system over the edge

Question 8

What are Capsules?

Answer 8

Ridgid, may have a waxy consistency
prevents external damage
prevents water loss

Question 9

What is the Slime layer

Answer 9

Mucous/jelly layer around the cell

attatchment

Question 10

What are Flagella?

Answer 10

Tail like extensions of the cell
can come in multiples
whips back and forth to propel the cell
extremely chaotic (run tumble run mechamism)

Question 11

What are Pili?

Answer 11

Many, All over the surface
attatchment
can be used to exchange genetic information.
(looks like a bridge)
