Unicellular - made up of ONE cell like bacteria & amoeba, Multicellular - made up of MORE than one cell like animals & plants, Hypothesis - An educated guess that is testable, Theory - An explanation of WHY, Law - An observation of WHAT, Mitochondria - in BOTH plant & animal cells, powerhouse of cell, breaks down sugar to release energy, Chloroplasts - in plant cells, capture energy from sunlight & turns into chemical energy, stored food in photosynthesis, Cytoplasm - Jelly substance that supports & protects cell's organelles outside nucleus, Active Transport - Movement of molecules that requires energy, Carrier protein - transports specific molecules across the cell membrane, Cell - Basic structure & function of life, Cell membrane - contains movement of materials in/out of cell & maintains homeostasis, Cell Wall - In plant & prokaryotic cells, located outside cell membrane, adds support & protection, Centriole - barrel shaped organelle, in eukaryotic cells, composed of microtubules arranged in nine symmetry, Channel proteins - Protein channel that is always open, Cholesterol - waxy substance found in body's cells & blood, Diffusion - Movement of molecules without the use of energy, Endocytosis - cells take in particles by engulfing, IN, BIG, Osmosis - Movement of water from high to low concentration, Endoplasmic Reticulum - network of membranes in eukaryotic cells synthesizing proteins & lipids, transports within cell, Exocytosis - Movement of large molecules out of the cell with aid from the membrane, Facilitated Diffusion - passive transport solute move down their concentration (HIGH to LOW) needs help from protein channels, Glycolipid - lipid with attached carb molecule, crucial for cell membrane & function, Glycoprotein - protein with one or more carb chains attached, Homeostasis - maintenance of relatively constant internal conditions, Hydrophilic - substance attracted to, dissolves in, able to be wetted by water, has high affinity for water, Hydrophobic - Water-hating, Hypertonic - Movement of water out of the cell; solution has higher solute concentratior, Hypotonic - Moves in, Isotonic - Movement of water is 0; homeostasis is achieved,
