Centriole Function
Makes Microtubules
3 Types of Cytoskeleton
Microtubules
Microfilaments
Intermediate Filaments
Microtubules
are the “roads” of the cell
Microfilaments
give the plasma membrane shape
Intermediate Filaments
anchored at a certain point on plasma membrane
Microvilli
increase surface area of membrane
Cilia
made of microtubules
move substances across cell
Glycocalyx
carbohydrate
identifies the cell, like its “flag”
Cholesterol
Keeps the plasma membrane fluid
Phospholipid bilayer
Hydrophilic heads
Hydrophobic tails
Polar Molecules Rejected
Non Polar Molecules Pass Through
Simple Diffiusion
Non-Polar Molecules Moves Directly Across Membrane
Facilitated Diffusion
Non-Polar Molecule passes through Integral Protein Channel from a High to Low Concentration
Osmosis
Water moves across membrane from high concentration to low concentration
Carrier Mediated Active Transport
Carrier protein uses ATP to move molecule against concentration gradient
Vesicular Transport
Cell engulfs or expels material through
Endocytosis - phagocytosis (solid), pinocytosis (liquid)
Exocytosis -
Membrane Junctions
Tight Junction - creates seal
Desmosome - link prevents cell from ripping apart
Gap Junctions - allows molecules to pass through. Quick communication
