Cells

QuestionAnswer
cell theory all cells come from existing cells, cells are the basic unit of life, all living things are made up of cells
What scientist discovered the plant cell? Matthias Schleiden
nucleus function contains genetic information for making proteins
rough ER function helps proteins fold and are prepared for release from the cell or to the Golgi
mitochondria function releases energy from food and is the site of ATP production
lysosomes function contains digestive enzymes to break down waste
golgi bodies function packages and processes proteins and lipids sending them to the rest of the cell
cell membrane function selectively regulates what enters and leaves the cell
cytoskeleton function anchors the organelles to the cell membrane; provides structure
cilia shorter, short hair-like projections that help the cell move, found in organisms such as paramecium, more numerous (cover the cell in larger numbers)
flagella longer, long thread-like structures that are found at the end of the cell to help it move, found in organisms such as bacteria and sperm cells, less numerous
what structures are found in only plant cells, not animal cells cell wall, chloroplast, large vacuole
vacuole differences in animal and plant cells while plant and animal cells both have vacuoles, the plant cells' vacuoles are much larger to store water
describe prokaryotes and eukaryotes both have DNA and both make proteins, prokaryotes DNA in nucleoid, eukaryotes DNA in nucleus, no nucleus or membrane-bound organelles in prokaryotes
endosymbiotic theory smaller prokaryotes form a symbiotic relationship with the ancestral eukaryote which leads to the creation of more specialized cells
what organelles are part of the endosymbiotic theory mitochondria
similarities of capsids and nuclear membranes both protect genetic information for the structures
Small grain-shaped organelles that produce proteins for the cell Ribosomes

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.
