TermDefinition
CELL THEORY ALL living things have 3 basic parts (1) Come from pre­existing cells (2) Made up of cells (3) Cells are the basic unit
CELL TYPES Prokaryotic Cell and Eukaryotic Cell
PROKARYOTIC CELL A bacteria cell with no nucleus Does have DNA Does have a cell wall outside cell membrane
EUKARYOTIC CELL Includes ALL other cells Has a membrane-covered nucleus DNA stored in the cell nucleus Other organelle — mitochondria for cellular respiration
CELL MEMBRANE Surrounds cell Holds the cell together Allows SOME molecules to pass through
NUCLEUS Contains DNA It is the Control Center and Directs Cell Activity Found in Eukaryotic Cells
MITOCHONDRIA "Powerhouse" of the cell Conducts cellular respiration (energy)
CELL WALL Found in Plant cell Cell Wall around the cell membrane Provides structure and support
CHLOROPLAST Found in Plant cell Contains chlorophyll Photosynthesis occurs here
CELIA Found in Animal cell Short hair-like extensions Found on cell surface Used for locomotion (movement) AND food gathering
FLAGELLA Long hair-like (whip) extensions on the cell surface Used for locomotion (movement)
PLANKTON Microscopic plant and animal organisms Drifts freely in the upper ocean waters Capable of growing and reproducing
PHYTOPLANKTON Microscopic plant Drifts freely in the upper ocean waters Capable of growing and reproducing
ZOOPLANKTON Microscopic animal organisms Drifts freely in the upper ocean waters Capable of growing and reproducing
ATP (Adenosine Triphosphate) A high-energy molecule found in every cell Its job is to store and supply the cell with needed energy. It is where our cells get the energy needed to perform its tasks. Found in the cytoplasm 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.
