2 Types of Cells2 Types of Cells1.1. ProkaryoteProkaryote – –
no organelles, no organelles, only DNA and only DNA and ribosomes, Ex: ribosomes, Ex: Bacteria and Bacteria and ArchaeArchae
2.2. EukaryoteEukaryote – – true cells with all true cells with all organelles, Ex: organelles, Ex: plants, animals, plants, animals, protists, fungiprotists, fungi

•Facilitated diffusionFacilitated diffusion – carrier – carrier proteins help molecules across proteins help molecules across the cell membrane ex: insulin the cell membrane ex: insulin helps sugarhelps sugar
•Ion channelsIon channels – gates for Na & K – gates for Na & K

•IsotonicIsotonic – equal solute in&out of – equal solute in&out of cellcell
•HypertonicHypertonic – more solute outside, – more solute outside, cell shrivels ex: salt watercell shrivels ex: salt water
•Hypotonic Hypotonic – more solute in cell, – more solute in cell, cell swellscell swells
•Water always goes toward solute!!Water always goes toward solute!!
