QuestionAnswer
1 Polar Uneven distribution of charge
2. Cohesion Attractions between particles of the same substance
3. Adhesion Attraction between particles of different substances
4. Hydrogen bond Force of attraction between a hydrogen with a partial positive charge and a molecule with a partial or full negative charge
5. Hydroxide Ion an OH- ion
6. Hydronium ion The H3O+ ion, The number of these determines the acid or alkalinity in a solution
7. Acid A solution that has more hydronium ions than hydroxide ions
8. Base As solution that has more hydroxide ions than hydronium ions
9. PH scale The scale which measures the concentration of hydronium and hydroxide ions in a solution
10. Buffer A chemical substance that neutralizes small amounts of acids or bases
11. Organic compounds Made primarily of carbon
12. Monomer A smaller simpler molecule that makes up carbon compounds
13. Polymer A molecule that is made of repeated linked units
14. Condensation reaction The chemical reaction that causes monomers to form polymers
15. ATP adenosine triphospate, the compound that stores energy for cells
16. Carbohydrate An organic compound formed of 1 oxygen and 1 hydrogen atom and 2 carbon atoms
17. Monosaccharide A monomer made of a carbohydrate, also called a simple sugar
18. Disaccharide When two monosaccharides combine to make a double sugar
19. Polysaccharide Made of 3 or more monosaccharides
20. Protein Compound formed of carbon, nitrogen, oxygen and hydrogen. Made of amino acides
21. Amino acid Type of monomer that makes up protein
22. Peptide bond When two amino acids form a covalent bond
23. Polypeptide When amino acids form very long chains
24. Enzyme RNA molecules that act as biological catalysts
25. Substrate The reactant that is catalyzed by the enzyme
26. Active site The folds of an enzyme that allows substrate to fit into it.
27. Lipid Large nonpolar organic molecules that don't dissolve in water
28. Steroid A lipid that is formed with 4 fused carbon rings
29. Nucleic acid Very large and complex organic molecule that stores and transfers important info in the cell
30. nucleotide Linked monomers that make up RNA and DNA
31. Cell The smallest unit that can carry on all life processes
32. Cytoplasm The internal region of the cell that includes all organnelles except the nucleus
33. Cytosol The part of the cytoplasm that includes molecules and small particles but not organelles
34. Prokaryote Organisms that don't have a membrane contained nucleus or organelles
35. Eukaryote Multicellular organisms that have membrane contained nucleus and organelles
36. Organelle Subcellular structures that perform specific duties inside the cell
37. Cytoskeleton Network of thin tubes and filaments that give shape to a cell
38. Microtubule Hollow tubes within a cell made of a protein called tubulin
39. Microfilament Long threads of the beadlike protein actin that are linked end to end and wrapped around each other like strands of a rope and contribute to cell movement
40. Cilium Hairlike structures that extend from the surface of the cell and aid in cell movement - they are short and there are many
41. Flagellum Hairlike structures that extend from the surface of the cell and aid in cell movement - they are long and there are few
42. Plastid Organelles that are surrounded by a double membrane and contain their own DNA. Includes chloroplasts, chromoplasts, leucoplasts

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.
