7740247124Cell Membranephospholipid bi layer, holds the cell together, found in all cells0
7740257593Cell Wallmade of cellulose and protein, functions as structure for cells and protects cell from mechanical damage. Found only in plant cells (eukaryotes) and bacterial cells (prokaryotes)1
7740270269NucleusSurrounded by nuclear envelope, contains DNA (chromatin) and the nucleolus. Found in plant and animal cells2
7740270270Nucleoluslocated inside the nucleus; makes ribosomes in plant and animal cells3
7740289821Ribosomesfound as free ribosomes floating in the cytoplasm as well as bound ribosomes attached to the rough endoplasmic reticulum. Makes proteins in plant and animal cells4
7740304160Rough ERmembranes with bound ribosomes, attached to the nuclear envelope. makes and folds proteins in plant and animal cells5
7740323586Smooth ERmembranes without ribosomes, makes lipids for cell membrane, metabolism of carbohydrates and is important for detoxification in plant and animal cells6
7740346100Golgi apparatusmodifies, sorts, packages, and ships out proteins in plant and animal cells. active in synthesis7
7740357691Mitochondriadouble membrane with lots of internal folds, which is important for converting glucose to ATP energy (cellular respiration) in plant and animal cells8
7740375087Chloroplastdouble membrane with stacks of disks called thylakoids, converts solar energy to chemical energy stored in the bonds of glucose (photosynthesis) in plant cells9
7740405291Lysosomesvacuoles with hydrolytic enzymes that break down food and/or parts of the cell to be recycled. Transports proteins in animal cells -pH of 4.5-5.010
7740440308central vacuolestores water within plant cells11
7740482147transport vesiclecarries secretions for export from the cell, from the Golgi apparatus, carries proteins from the ER to the Golgi apparatus12
7740515155smooth ermakes cell membrane13
7740519773nucleuscell's control center14
7740539344plasma membranea substance must pass through here to enter or leave a cell15
7740546486bacteria and archaeaconsists of prokaryotic cells16
7740625748all cells have...cell membrane, cytoplasm, DNA, and ribosomes17
7740686360prokaryotic cellsno nucleus, no membrane bound organelles, evolved first, bacteria, DNA in cytoplasm (nucleoid)18
7740704148eukaryotic cellstype of cell that contains a nucleus bound by a double membrane, evolved later, is found in plants, animals, protists, and fungi, contains membrane bound organelles19
7740728379Endomembrane Systemcontains ER, Golgi apparatus, lysosomes, peroxisomes, vacuoles, and vesicles. Synthesizes, packages, exports/imports materials to and from the cell20
14803355925peroxisomeorganelle with various specialized metabolic functions; produces hydrogen peroxide as a by-product, then converts it to water. found in plant and animal cells21
14803368847cytoskeletoninternal infrastructure of cells made of small proteins, reinforces shape and functions in cell movement22
14803391237translationProcess by which mRNA is decoded and a protein is produced in ribosomes23
14803393707free ribosomesribosomes suspended in the cytoplasm, make proteins that are needed by THAT CELL24
14803408505bound ribosomesfound on the endoplasmic reticulum, makes proteins destined for secretion for OTHER cells to use25
14803430483glycolipids and glycoproteinshelp cells communicate and recognize each other26
14803526980Phagocytosisprocess in which extensions of cytoplasm surround and engulf large particles and take them into the cell27
14803531216AutophagyA process in which lysosomes decompose damaged organelles to reuse their organic monomers, which are released into the cytosol28
14803545176contractile vacuolepumps excess water out of the cell29
14803552048Endiosymbiontcell living within another cell30
14803556395endiosymbiont theorytheory stating that eukaryotic cells formed from a symbiotic relationship with several different prokaryotes (mitochondria and chloroplasts) by engulfing an oxygen using prokaryotic cell31
14803587527Why is the inner membrane of mitochondria highly folded? What is the role of the individual thylakoid membranes?to expand the cell's surface area32
