3 Major parts of the cell - nucleus, cytoplasm, cell membrane
Nucleus - Control center of the cell, contains DNA
Cytoplasm - consists of cytosol and organelles
Cell membrane (plasma membrane) - encloses the cell, regulates the passage of
materials into and out of the cell. Selectively permeable, made up of lipids and proteins
phospholipid bilayer - a two-layered arrangement of phosphate and lipid molecules that
form a cell membrane.
Hydrophobic lipid tails facing inward and the hydrophilic phosphate heads facing outward.
Hydrophobic - Water fearing, insoluble in water
Hydrophilic - Water loving, water soluble
Phospholipid bilayer is made of... - phosphate, lipids, protein
Cytoskeleton - A SUPPORTING FRAMEWORK of protein rods and tubules
Lysosomes - Garbage disposal of the cell, cleans up waste inside the cell
Ribosomes - Makes proteins
Smooth Endoplasmic Reticulum (SER) - Makes lipids
Rough Endoplasmic Reticulum (RER) - studded with ribosomes and involved with protein
synthesis
Golgi apparatus - Packages and ships out proteins. "UPS/Amazon"
