596177960to enter or leave a cell, substances must pass througha plasma membrane
596177961is a nucleus a part of the cytoplasmno
596177962maximum size of a cell is limited byits need for enough surface area for exchange with its enviornment
596177963a cell with an extensive golgi apparatus wouldsecrete a lot of material
596177964cellular metabolismthe chemical activity of the cell
596177965what is the internal skeleton of a cell composed ofmicrotubules, intermediate filaments, and microfilaments
596177966dye injected into a cell might be able to enter an adjacent cell through a..., in plant tissuesplasmodesma
596177967if a cell's chromatin were damaged, the cell wouldgo out of control
596177968garbage disposal of the celllysosome
596177969electron microscopes are helpful in studying prokaryotes becauseprokaryotes are so small
596177970a plant cell unable to manufacture cellulose would be unable tobuild a cell wall
596177971Contains chromatin, where chromosomes are found, used in DNA synthesis, RNA synthesis, assembly of ribosomal subunits in nucleoli, the control center for cell metabolism and reproduction.Nucleus
596177972Polypeptide syntesis, nonmembraneous organelle, small structure that makes protein,Ribosomes
596177973Synthesis of membrane proteins, secretory proteins, and hydolytic enzymes; formation of transport vesicles, makes cell membrane, proteins are made here to be secreted from the cellRough ER
596177974Lipid are manufactured here, carbohydrate metabolism in liver cells, calcium ion storage, breaks down drugs and toxins in liver,Smooth ER
596177975surface for chemical activity, serves as a pathway for the transport of materials through out the cell; also associated with synthesis and storageEndoplasmic Reticulum
596177976Modification, temporary storage, and transport of macromolecules, formation of lysosomes and transport vesicles, ships products to the plasma membrane, outside, or to other organelles storage center for secretory materialsstores and releases chemicalsGolgi Apparatus
596177977digestion of nutrients, bacteria, and damaged organelles, destruction of certain cells during embryonic development, in animal cells and some protists only, sac of enzymes that digest things, digests foods, wastes and foreign substancesLysosomes
596177978breaks down fatty acids in oxidation, diverse metabolic processes with breakdown H2O2 by-product, can break down alchohol/absorb it in liverPeroxisomes
596177979digestion, storage of chemicals, cell enlargement, water balance, conrains codes that guide all cells,Vacuole
596177980Helps plant cell grow in size, May store water, needed chemical, wastes, pigments in plant cellsCentral Vacuole
596177981collects excess water and waste in the cell and expels itContractile Vacuole
596177982converts light energy into chemicala energy of sugars, in plants and some protists, photosynthesizing organeles of plants and protistsChloroplasts
596177983conversion of chemical energy to food energy or ATP, the "powerhouse" of the cell, cellular respirationMitochondria
596177984Maintinence of cell shape, anchorage for organelles, movement of organelles within cells, mechanical transmission of signalsfrom exterior to interior, has microtubules, microfilaments, amd intermediate fibers, includes cilia, flagella, and centrioles in animal cellsCytoskeleton
596177985maintenance of cell shape and skeletal support, surface protection, binding of cells in tissues,in plants, some fungi, and some protists, not in animal cells,Cell Wall
596177986Binding of cells in tissues, surface protection, regulation of cellular activities, in animalsExtracellular Matrix
596177987prokaryoteshave a nucleoid region, smaller, bacterial and archaeic
596177988eukaryotesnuclei, bigger, membrane bound organelles, animal
596177989DNA of a prokaryotic cell is coiledin thenucleoid region
596177990Pilishort projections that help attach prokaryotes to surfaces
596177991Prokaryotic Flagellapropel the prokaryotic cell through its lipid enviornment
596177992thick fluid-filled region between the nucleus and plasma membranecytoplasm
596177993DNA is attached to proteins froming very long fiberschromatin
596177994adjoining the chromatin within the nucleus is a mass of fibers and granules, located in the nucleus and it synthesizes parts of ribosomesnucleolus
596177995when a molecule is ready for export from the ER, it is packaged in a tiny sac called atransport vesicle
596177996inner membrane is highly folded, and enzyme molecules that make ATP are embedded in in. The folds increase the membrane's surface area, enhancing the mitochondrions ability to produce ATPcristae
596177997Microfilamentssolid helical rods that are composed mainly of globular protein called actin, help cells chanfe shape and move by assembling at one end while disassembling at the other
596177998Intermediate FilamentsMade of fiborous proteins rather than globular ones and have a ropelike structure, serve mainly as reinforcing rods for bearing tension ans also help anchor certain organelles
596177999Microtubulesstraight, hollow tubes composed of globular proteins called tubulins, they elongate by adding subunits consisting of tubulin pairs, they arre an anchorage for organelles and to act as tracks for organelle movement within the cytoplasm
596178000ciliashort numerous appendages that propel protisrs
596178001flagellalonger, generally less numerous appendages on other protists
596178002cell junctionsto function in a coordinated way as part of a tissue, the cells need structures that connect them to one another
596178003tight junctionbind cells together forming a leakproof sheet, lines the digestive tract
596178004anchoring junctionattach adjacent cells to each other or to the extracellular matrix
596178005communicaing junctionchannels similar in function to the plasmodesmata of plants, allows water and small molecules to flow between neighboring cells
596178006anabolicbuilding
596178007catabolicbreaking
596178008describe the pathway of hydrolysis enzymes as they are mademade in ribosimes on rough er, put in vesicle, on to the golgi and put in a vesicle to become a lysosome
596178009what structures have a 9+2 arrangementflagella and cilia
596178010what structures have hydrolysis enzymeslysosomes
596178011what structures contain pigmentplastids
596178012which organelle has grana/thylakoidschloroplasts
596178013why does cytoplasmic streaming occurchloroplasts are mosly toward the light so they can see photosynthesis
596178014why is it called a 9+2 patternthe microtubules are in 9 pairs around 2 macrotubles
