How does nucleus stain and why?
Darker since more acidic
“basophilic”
Chromatin (types & structure)
Heterochromatin: condensed, inactive
Euchromatin: dispersed, active
Nucleolus function & structure
F: making ribosomal RNAs
S: nuclear organized=lighter stain, central
Cell membrane (plasmalemma) function & structure
Function: selective barrier, selective transport, sensor
Structure: lipids- barrier to water, messengers
proteins- enzymes, channel proteins, receptors
carbohydrate- glycocalyx
Endocytosis Types
Pinocytosis: non-selective, takes in volume from outside (“cell drinking”)
Receptor-mediated: selective, binding to receptors=transport
Phagocytosis: membrane surrounds & enclosed in cyto
