QuestionAnswer
Central Vacuole reproduction, growth, and development in plant cells
Chloroplast organelle
Integrin in animal cells, a transmembrane receptor protein that interconnects the extracellular matrix and the cytoskeleton
Chromosome cellular structure that carries genetic material, found in the nucleus of eukaryotic cells
Rough ER studded with ribosomes
Fibronectin glycoprotein that helps animal cells attach to the extracellular matrix
Microtubule hollow rod composed of tubulin proteins that make up part of the cytoskeleton in all eukaryotice cells and is found in cilia and flagella

Centrosome important during cell division
Nucleoid dense region of DNA in a prokaryotic cell
Nuclear Lamina protein filaments lining the inner surface of the nuclear envelope
Secondary Cell Wall Strong durabe matrix, several layers for cell protection and support
Chromatin long thin fibers
Primary Cell Wall thin flexible layer
Lysosome sac of hydrolytic enzymes found in the cytoplasm of animal cells
Collagen extrcellular matrix of animal cells that forms strong fibers, found in connective tissue and bone
Granum stack of membran-bounded thylakoids in the chloroplast
Intermediate Filament component of the cytoskeleton that includes filaments intermediate size between microtubules and microfilaments
Endomembrane System collection of membrans inside and around a eukaryotic cell
Stroma dense fluid of the chloroplast surrounding the thylakoid membrane
Nuclear Envelope encloses the nucleus
Organelle several membran-enclosed structures with specialized functions
Cell Fractionation disruption of a cell and seperation of its parts by centrifugation
Dynein a large contractile protein extending from one microtubul doublet to the adjacent doublet
Plastid photosynthetic organelles
Gap Junction in animals that allows the passage of materials between cells
Ribosome rRNA and protein molecules that functions as a site of protein synthesis in the cytoplasm
Contractile Vacuole memranous sac that helps move excess water out of certain freshwater protists
Cytoskeleton serves a variety of mechanical, transport, and signaling functions
Plasma Membrane selective barrier, regulating the cell's chemical composition
ACtin globular protein that links into chains
Desmosome a type of intercellular junction in animal cells that functions as a rivet
Smooth ER free of ribosomes
Centriole a cylinder of microtubule triplets arranged in a 9+0 pattern
Crista infolding of the inner membrane of a mitochndrion that houses electron transport chains
Peroxisome contains enzymes that transfer hydrogen from various substrates to oxygen
Food Vacuole formed by phagocytosis of microorganisms or particles to be used as food by the cell
Cytoplasmic Streaming circular flow of cytoplasm, involiving myosin and actin filaments
Thylakoid flattened membranous sac inside a chloroplast
Plasmodesma open channel in the cell wall of a plant through which strands of cytosol connect from an adjacent cell
Nucleolus specialized structure in the nucleus

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
