Cell organelles/type

study guide for cell types, differentiation and homeostasis quiz

QuestionAnswer
mitochondria cell organelle responsible for energy production (respiration), folds in membrane to increase surface area.
Plant cell eukaryotic, cell wall, chloroplast, bigger, large vacuole
Prokaryote no nucleus, no membrane organelle, smaller cells, examples are bacteria cells. CONTAIN RIBOSOMES
Eukaryote nucleus, membrane bound organelle, larger cells examples are plants and animals
ribosomes responsible for protein synthesis. PRESENT IN ALL CELLS!
Plasmids circular DNA in bacteria cells
animal cells eukaryotic, plasma membrane, centrioles, many small vacuoles, NO cell wall or chloropolast
plasma membrane determines what substance can enter an leave a cell. ALL cells have plasma membranes
differentiation the process where an egg cell is able to form many different types of cells. Example muscle, nerve, sperm, blood cells all come from the same egg cell
nucleotides sub units of DNA that store genetic information
how differentiation occurs different cells are able to come from 1 undifferentiated cell because different genes are activated in different cells
lipids (fats) used for energy storage and insulation
If the objective is 40x and the eyepiece is 10x what is the total magnification? 400x
active transport movement of molecules from a low to a high concentration with the use of energy
passive transport movement of molecules from high to low concentration no energy required. Includes osmosis, diffusion, and facilitative diffusion
osmosis movement of water from a high to a low concentration
facilitative diffusion movement of very large molecules from an area of high to an area of low concentration with the help of carrier proteins. No energy required
buffers molecules that prevent rapid changes in pH

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.
