SBS cells

cell parts and functions

TermDefinition
Cell membrane thin, flexible barrier that surrounds a cell and controls which substances pass into and out of a cell.
Cytoplasm constantly moving gel-like mixture inside the cell membrane that contains hereditary material and is the location of most of a cell's process
Cell wall tough, rigid outer coverings that protect the cell and give it shape (plants, fungi, algae, most bacteria)
Organelle structure in the cytoplasm that can act as a storage site, process, energy, move materials,or manufacture substances.
Nucleus organelle that controls all the activities of a cell and contains hereditary material made of protein and DNA
Chloroplast green, chlorophyll-containing, plant cell organelle that converts sunlight, carbon dioxide, and water into sugar
Mitochondria cell organelle that breaks down lipids and carbohydrates and releases energy. rod-shaped structures (singular: mitochondrion)
Ribosome small structure in which cells make their own proteins
Endoplasmic reticulum organelle that processes substances (including proteins and lipids) around the cell, and is made up of folded membranes, can be rough (ribosomes attached) or smooth (no ribosomes attached)
Golgi bodies organelles (looks like flattened sacs and tubes) that package cellular material (received from the ER)and transports them within the cell or out of the cell
tissue group of similar cells that work together to do one job.
Organ structure made up of different tissues (heart)that work together
Prokaryotic cell cells without membrane bound structures; no nucleus; archaea and bacteria
Eukaryotic cell cell with membrane bound structures; have a nucleus.
lysosome organelle that contains digestive chemicals that help break down food molecules, wastes and worn out cell parts (cell's recycling centers)
nucleolus produces ribosomes which leave the nucleus and attach to the endoplasmic reticulum (important for protein synthesis)
vacuole a sac-like organelle that stores food, water, or other materials needed by the cell. Also store waste products. Smaller in an animal cell than a plant cell.
Order of organization for a multicellular organism cells--> tissue-->organ--> organ system--> organism

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.
