Cell Notes

Cell structures and functions

StructureFunction
Cell Wall ◊Animal cells don't have one ◊Plants: made of cellulose ◊Gives strength structure and rigidity to plant thru Turgor Pressure
Cell Membrane ◊Outside covering ◊Determines what goes in/out of cell ◊Flexible but supports cells
Vacuole ◊Storage unit in cells that hold water ◊Large in plants, small in animal cells
Nucleus ◊Control center of cell ◊Houses DNA ◊Controls cell growth and makes ribosome
Mitochondria ◊"Power House of the cell" ◊Produces energy (breaks down glucose) ◊C6H12O6 + O2 + CO2 + H2O + Energy
Cytoplasm ◊Gelatinous, semi-transparent fluid that fills the cells ◊Organelles are suspended in cytoplasm
Chloroplast ◊Only Found in Plants ◊Site of Photosynthesis: captures radiant energy and converts it to chemical energy ( C6H12O6) AKA- glucose ◊Has chlorophyll- green pigment that absorbs light
Prokaryote ◊A single-celled organism with NO Nucleus ◊DOES have DNA ◊No other specialized organelles ◊Eubacteria and Archaebacteria
Eukaryote ◊Has a Nucleus that contains DNA ◊Single or multicellular ◊Has membrane bound organelles ◊Includes all living organisms other than the eubacteria and archaebacteria
Cell Theory ◊All living organisms are composed of one or more cells ◊The cell is the most basic unit of life ◊All cells arise form pre-existing, living cells
Lysosome ◊Contains digestive enzymes to break things down in cell
Rough Endoplasmic Reticulum ◊Covered in ribosomes, stores proteins
Smooth Endoplasmic Reticulum ◊(No ribosomes) transports cell products
Ribosome ◊Site of Protein Synthesis
Golgi Body ◊Packages cell products for transport (Like UPS)

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.
