�CHEAT SHEET 2: Cells & Cell Processes
Prokaryotes vs Eukaryotes
Prokaryotes: small, no nucleus, simple bacteria
Eukaryotes: nucleus, organelles, plants/animals/fungi
Organelles
Nucleus: DNA storage
Mitochondria: ATP production
Chloroplasts: photosynthesis
Ribosomes: protein synthesis
Golgi: modifies & packages proteins
ER: rough = ribosomes, smooth = lipids
Lysosomes: digestion
Cell membrane: phospholipid bilayer
Transport
Passive: diffusion, osmosis, facilitated diffusion
Active: requires ATP, moves against gradient
