Biology Vocab Quiz

TermDefinition
diffusion molecules move from a more molecule concentrated area to a less molecule concentrated area
exocytosis process in which cells release large amounts of material
phagocytosis extensions of cytoplasm surround and engulf large particles and take them into the cell
pinocytosis a cell takes in liquid from the surrounding environment
concentration the mass of a solute in a given volume of solution, or mass/volume
cell wall strong supporting layer around the cell membrane in plants, algae, and some bacteria
organ system group of organs that work together to preform a specific function
equilibrium when the concentration of a solute is the same throughout a solution
lipid bilayer double-layered sheet that forms the core of nearly all cell membranes
eukaryote organism whose cells contain nuclei
cell membrane thin, flexible barrier around the cell; regulates what enters and leaves the cell
endocytosis cell takes material into it by infolding the cell membrane
cell specialization cells develop in different ways to preform different tasks
cell theory -all living things are composed of cells -cells are the basic units of structure and function -new cells are produced from existing cells
hypertonic the solution with the greater concentration of solutes, when comparing two solutions
tissue group of similar cells that preform a particular function
nucleus structure that contains the cell's DNA; the control center
cell collection of living matter enclosed by a barrier; basic units of all forms of life
active transport process that moves material across a cell membrane against a concentration difference
osmosis diffusion of water through a selectively permeable membrane
organ group of tissues that work together to preform closely related function
isotonic when the concentration of two solutions is the same

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.
