TermDefinition
Cell membrane double-layer of phospholipids that forms a boundary between a cell and the surrounding environment
Nucleus organelle found in eukaryotes that stores genetic information (DNA)
Cytoplasm Jelly like fluid found in the inside of the cell
Mitochondria bean-shaped organelle that supplies energy in the form of ATP to the cell
Golgi body (apparatus organelle that sorts and delivers the proteins in the cell
Cytoskeleton network of microtubules that gives the cell support and shape
Lysosome organelle that uses enzymes to break down materials in the cell
Ribosome site of protein synthesis (where proteins are created)
Rough endoplasmic reticulum Organelle that is rough because of the proteins found on the outside. Proteins are distributed
Smooth endoplasmic reticulum no proteins found on the surface. Proteins are distributed
Vacuole organelle that stores water, food or enzymes in the cell. LARGER in PLANT Cells
Vesicle small organelle that transports materials into and out of the cytoplasm
Cell wall Out layer of covering that protects the cell. It is ONLY found in plant cells
Chloroplast organelle that converts light energy (from the sun) into energy to be used by the plant
Centriole/ Centrosome small cylinder-shaped organelle made of protein tubes arranged in a circle; aids mitosis.
Prokaryote cell that has NO nucleus and NO membrane-bound organelles.
Eukaryote cell that has a nucleus and membrane-bound organelles.
Cell theory the theory that states all organisms are made of cells, all cells are produced by other living cells, and the cell is the most basic unit of life.
Cell smallest unit of life
Bacteria type of prokaryotic cell
Endosymbiosis ecological relationship in which one organism lives within the body of another
Active transport Type of transport that DOES require energy to move molecules
Passive transport Type of transport that does NOT require energy to move molecules
Diffusion movement of dissolved molecules across the cell membrane from a region of higher concentration to a region of lower concentration.
Osmosis movement of water molecules across the cell membrane from a region of higher concentration to a region of lower concentration.

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.
