Cytology

Cell parts

WhoWhatDo
Cell Membrane semipermeable, bimolecular layer of lipids/fats Controls transport of molecules into the cell
Cytosol/Cytoplasm thick solution of water proteins, fats, carbohydrates and inorganic salts forms environment for cell reactions
Nucleus spheroind bound by 2 porous membranes holds genetic material
Cell Membrane semipermeable, bimolecular layer of lipids/fats Controls transport of molecules into the cell
Cytosol/Cytoplasm thick solution of water proteins, fats, carbohydrates and inorganic salts forms environment for cell reactions
Nucleus spheroid bound by 2 porous membranes holds genetic material and controls activity of the cell and it's organelles
Chromatin dispersed, thready DNA and Protein gentic material within the nucleus
Chromosomes (during cell division) condensed and coiled chromatin gentic material within the nucleus
Nucleolus round mass(es) of RNA within the nucleus gentic material within the nucleus
Smooth Endoplasmic Reticulum double layered, wavey channels connecting the nucleus and the cell membrane - NO Ribosomes synthesis of carbohydrates and fats
Rough Endoplasmic Reticulum double layered, wavey channels connecting the nucleus and the cell membrane - MANY Ribosomes synthesis and temporary storage or transport of proteins
Golgi Complex flattened, stacked membranous sacs secrete protein (hormones) to outside of cell - where WBC come from
Mitochondria rod-shaped, membrane-bound "powerhouses" glucose + O2 + H2O -----> ATP + CO2 + H2O
Lysosomes granular sacs containing digestive enzymes - "suicide bags" digest bacteria that enter the cell - remove damaged organelles - detoxitfy
Microtubules straight bundled hollow tubes serve as internal support or transport channels within the cell - form/are cillia, flagella, and mitotic spindles
Organelles membrane/non-membrane bound structures unique to their activities carry out specific metabolic activities of the cell

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.

To see how well you know the information, try the Quiz or Test activity.
