5249489274Prokaryoticsmaller organelles NOT membrane-bound nucleoid instead of nucleus0
5249510131Eukaryotic10x bigger than prokaryotic organelles ARE membrane-bound have nucleus1
5249527826TEMTransmission ELectron Microscope Electrons transmit through- used to study the internal ultrastructure of cell2
5249534427SEMScanning Electron Microscope Electrons scans the surface3
5249556497Cell Fractionationuse centrifuge heaviest material goes to bottom4
5249586983Plant cells carry out both...respiration and photosynthesis5
5249591715All cells have... (4 things)plasma membrane Cytsol DNA/Chromosomes Ribosomes6
5249630030The nucleus is a double membrane. Inside, it's lined by NUCLEAR LAMINA.protein filaments that help the nucleus maintain shape7
5249998698Chromosomescoiled up chromatin fibers8
5249668825NucleolusStructure: within nucleus Function: constructing/assembling ribosomes ribosomal RNA is synthesized with proteins into ribosomal subunits9
5250016462RibosomesStructure: Located in ER Function: build proteins from amino acid monomers10
5250810356Free Ribosomessuspended in cytosol function within the cell11
5250825874Rough ERStructure: attached to nucleus and has ribosomes on it where proteins are made, and secrete proteins made by the ribosomes12
5250844368Smooth ERStructure: attached to rough ER produces lipids, and cholesterol also breaks down toxins (detoxification)13
5250855865Golgi Bodyfinishes, sorts, and ships cell products modifies and adds carbohydrates14
5250869403CIS facereceives material from the ER15
5250871039TRANS faceshipping side to travel to other sites16

5251150776peroxisomesdigestive component breaks down macromolecules REQUIRES oxygen hydroxide to water22
5250905979phagocytosisa process lysosomes carry out in order to break down food (endocytosis)23
5250920928pinocytosisvesicles break down fluids (endocytosis)24
5250965906facilitated diffusionpassive transport through transport proteins25
5250987997Active Transportrequires energy movement of molecules against gradient ex: sodium-potassium pump26
5250992374Passive Transportdoesn't require energy diffusion of substances across membrane27

5251031338Endocytosistakes in new macromolecules by forming new vesicles29
5251066996Microfilamentsthinnest of the 3 protein fibers made up of protein called actin involves cell movement maintains shape MUSCLE CELLS and PHAGOCYTES30
5251089149Intermediate FIlamentsslightly bigger than microfilaments found in nucleus maintains shape31
5251101389Microtubulesmade up of the protein tubulin found in spindle apparatus which guides the movement of chromosomes during cell division32
5251126281Flagellalong and few one of the 2 basal bodies33
5251126282Ciliashort and many one of the 2 basal bodies34
5251139950Plasmodesmata35
5251172688Animal cells prefer...isotonic36
5251174405Plant cells prefer...hypertonic (turgor pressure) doesn't like flaccid37

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
