0
Define Cytoplasm
Fluid environment inside the cell
Cytosol
maintains temperature
allows for chemical interactions to take place
(example full swimming pool vs empty)
1
Define Cytosol
Mixture of water & solutes.
2
What are plasma membranes
Physical boundary of the cells & controls interaction w/ the enviroment
protective & selective
(example water ballon)
3
What is the Nucleoid?
Region where the DNA is located
Chromosome
DNA
4
What are Ribosomes
Protein production site
non membrane bound organelle
common to both Eukaryotes & Prokaryotes
5
What are Inclusion Bodies?
Storage sites
6
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
7
Outer/External Membrane
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
8
What are Capsules?
Ridgid, may have a waxy consistency
prevents external damage
prevents water loss
9
What is the Slime layer
Mucous/jelly layer around the cell
attatchment
10
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)
