|
Cytoplasm
|
semefluid matric ( fills the enterior of the cell)
|
|
|
Plasma Membrane
|
lipid bilayer surrounding the cell
|
|
|
Gram Stain
|
All bacteria can be classified based on the differences in it cell wall
|
|
|
Flagelle
|
long thread like structures, used to move bacteria through the enviorment
|
|
|
peptoglyogin
|
Bacterial call wall is made of
|
|
|
Central Vacuole
|
large membrane sac bound; stores protiens, pigments and waste materials
|
|
|
Nuclear Pores
|
Depressions where the inner and outer membrane pinch together
|
|
|
Cristae
|
inner membrane (folded membrane) has many inside it
|
|
|
Matrix
|
Space inside the enter memebrane
|
|
|
Thylakoids
|
Disk shapped structures, have photosynthetic pigments on the surface
|
|
|
Stroma
|
fluid matrix surrounding the thylakiods
|
|
|
Phospholipids
|
form bilayer sheets in water, have one hydrophilic head and one hydro phobic Tail
|
|
|
Phospholipid Bilayer
|
layer in which all other membrane components are embedded. provides flexible matrix, and is a barrier to other molecules
|
|
|
Transmembrane Proteins
|
proteins that are embedded in the lipid bilayer. provide passage ways for molecules to pass in and out of the cell
Fpr |
|
|
Interior Protein network
|
provide support and reinforce the membrane’s shape
|
|
|
Cell surface Markers
|
act as identifying markers for cells, different cell types have different markers
|
|
|
Diffusion
|
dissolved molecules
|
|
|
solvent
|
the medium in which a solute is dissolved
|
|
|
solute
|
a molecule that is dissolved in a solvent
|
|
|
osmois
|
the diffusion of water; water will move from the side with the lower concentration of solute to the side with the higher concentration of solute
|
|
|
Hypotonic solution
|
has a lower concentration of solutes than a cell has inside it
Put a cell in a hypotonic solution it will GAIN water and swell |
|
|
Hypertonic solution
|
has a higher concentration of solutes than a cell has inside it
Put a cell in a hypertonic solution it will LOSE water and shrink |
|
|
Isotonic solution
|
has a equal concentration of solute as a cell has inside it
Put a cell in an isotonic solution and nothing happens, water passes in and out equally |
