|
All living things are made up of cells
All cells come from other cells Cells are the basic unit of living organisms |
|
Prokaryotic Cells
|
Have no nucleus; Circular DNA; Bacteria
|
|
Eukaryotic Cells
|
Have a nucleus and organelles; Ex Plants, animals, protists,
|
|
Plant Cells vs Animal Cells
|
plant cells have a central vacuole, cell wall, and chloroplasts
|
|
Composition of Membranes
|
Phospholipid bilayer w/ integral membrane proteins embedded in it
|
|
Passive Transport
|
uses concentration gradient and doesn't require energy (high-low)
|
|
Simple Diffusion/Osmosis
|
Small non-polar molecules & H²0 move across the phospholipid bilayer
|
|
Active Transport
|
Uses energy (ATP) and goes against the concentration gradient (low-high concentration)
uses pumps and vesicles |
|
Facilitated Diffusion
|
uses ion channels and carrier proteins to move large, polar, hydrophillic molecules
|
|
Endocytosis
|
Carries molecules into
|
|
Exocytosis
|
carry molecules out of
|
|
Hypertonic
|
has more solute; less H²O
|
|
Isotonic
|
has equal H²O and solute
|
|
Hypotonic
|
has less solute and more H²O
|
|
Solute
|
anything that's being dissolved
