unit test for cells

cell basic unit of all life
organelle specialized structures that perform important cellular functions
What is the difference between a eukaryotic and prokaryptic cell? prokaryotic cells do not have a nucleus and eukaryotic cells do have a nucleus.
What makes up the phosopholipid bilayer of a cell membrane? a phosphate head (water loving and a fatty acid tail (water fearing)
concentration The amount of salute in a solution. salute +solvent= salution
diffusion Moves small molecules into and out of the cell, moves from an area of high to an area of low concentration, does not use energy
facillitated diffusion Moves small molecules into and out of the cell, move from an area of high to and area of low concentration, uses protein channels, no energy
osmosis Moves small water only molecules into and out of the cell membrane by way of aquaporins, moves from an area of high to low concentration, no energy required
isotonic The concentration of two solutions are the same , equal
hypertonic The solution with the greater concentration of solutes, the cell shrinks
hypotonic the solution with the lesser concentration of salutes, the cell swells
Active transport Movement across the cell membrane, moves from low to high concentration, requires energy.
molecular transport movement across the cell membrane using protein pumps, moves large molecules from low to high concentration, requires energy
endocytosis movement of large molecules into the cell by engulfing the molecule, surrounding it with a vessicle and pulling it into the cell.
exocytosis the releasing of a large molecule by the cell into it's surrounding environment.
photosynthesis CO2 (carbon dioxide) +H2O (water) react to make the products C6H12O6 (glucose) + O2 (oxygen)
pigment Is a light absorbing molecule
Chlorophyll Pigment within plants and other photosynthetic organisms
What are the two main functions of the cell membrane? 1. controls what enters and leaves the cell maintaining homeostasis. 2. provides protection and support for the cell.
What are the three types of passive transport? 1. diffusion 2. osmosis 3. facillitated diffusion
What are the three types of active transport? 1. molecular transport 2. endocytosis 3. exocytosis
What direction will water diffuse based on the concentrations of two solutions? Water will diffuse to dilute the solute , water will move into the area with the highest concentration of salute.
What are the two forms of endocytosis? 1. phagocytosis-cell eating 2. pinocytosis-cell drinking
What are the three parts of an ATP molecule? 1. base-adenine 2. phosphates (3) 3. Bonds - energy is stored between the 2nd and 3rd bonds
What are the three factors that affect photosynthesis?

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.
