Cell Bio Cell Parts

plasma membrane - controls how molecules move in and out of cell - helps with cell-cell signaling and cell adhesion
nucleus - filled w/ chromatin - chromatin is made of DNA and proteins - location of mRNA and tRNA synthesis
nuclear envelope -double membrane - encloses nucleus contents - outer nuclear membrane is continuous with rER
nuclear pore allows specific large molecules to move between nucleus and cytoplasm
nucleolus - substructure of nucleus - most rRNA is made here - ribosomes are assembled here
mitochondria - powerhouse - generate ATP by oxidizing glucose and fatty acids - have their own DNA
lysosomes - have acidic lumen - degrade materials internalized by cell - breaks down small and large molecules in cell - release nutrients from digested food
peroxisomes - remove toxic molecules - break down fatty acids to make acetyl groups for biosynthesis
ribosomes - molecular machines - made of rRNAs and ribosomal proteins - translate mRNAs into proteins
endoplasmic reticulum, ER - located in cytoplasm - membrane-bound
rER - ribosomes bound to it - makes and sorts secretory, lysosomal, and some membrane-bound proteins
sER - no ribosomes attached - synthesizes lipids - detoxifies some hydrophobic compounds
golgi apparatus - processes and modifies proteins made by rER
vesicles - small, membrane-bound sacs - located in eukaryotic cytoplasm - specific ones are involved in secretion, exocytosis, endocytosis, and phagocytosis
microtubule - type of cytoskeleton - made of tubulin - helps organize cytoplasm - guides intracellular transport
centrosome - organizes microtubules - near nucleus in animal cells - forms the 2 poles of spindle in early mitosis
centrioles - cylindrical microtubules in centrosome of animal cells - also found in base of cilia and flagella (basal bodies)
actin filaments - type of cytoskeleton - major constituent of euk cells - helps w/ cell movement and muscle contraction
intermediate filaments - issa cytoskeleton type - form ropelike networks in animal cells - help resist outside tension ergo strengthens cell
extracellular matrix - complex networks of polysaccharides and proteins secreted by cells - structural component of tissues
chloroplasts - carries out photosynthesis by capturing sunlight - surrounded by double membrane - has internal membrane-bound sacs (thylakoids) - thylakoid contains chlorophyll -chlorophyll absorbs the light energy
vacuole - stores water, ions, nutrients - degrades macromolecules - helps w/ cell elongation during growth - 2 types: storage and lytic
cell wall - mostly made of cellulose - maintains cell's shape - protects cells against mechanical stress

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.
