Flashcards in Bacterial Structure of Prokaryotes Deck (12)
Fluid environment inside the cell
allows for chemical interactions to take place
(example full swimming pool vs empty)
Mixture of water & solutes.
What are plasma membranes
Physical boundary of the cells & controls interaction w/ the enviroment
protective & selective
(example water ballon)
What is the Nucleoid?
Region where the DNA is located
What are Ribosomes
Protein production site
non membrane bound organelle
common to both Eukaryotes & Prokaryotes
What are Inclusion Bodies?
What is a cell wall?
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
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
What are Capsules?
Ridgid, may have a waxy consistency
prevents external damage
prevents water loss
What is the Slime layer
Mucous/jelly layer around the cell
What are Flagella?
Tail like extensions of the cell
can come in multiples
whips back and forth to propel the cell
extremely chaotic (run tumble run mechamism)
