Test your basic knowledge |

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Produces megagametophyte that stays with sporophyte plant (produces egg)






2. More effective in stable environments - focus on fast growth without competition






3. Part of calvin cycle where ATP and NADH are turned into G3P (sugar)






4. Increase width (girth) of stems and roots - has vascular cambium and cork cambium






5. Sorting and shipping of molecules






6. A simple compound whose molecules can join together to form polymers






7. When xylem is blocked by air bubbles as a result of gasses clotting together after freeze-thaw cycles or extreme water-tension






8. Cell walls of cellulose - photosynthesis - indeterminate growth - asexual and sexual reproduction






9. Made of monosaccharides - building blocks of life - sugars






10. Attached directly by the base






11. Part of leaf for photosynthesis






12. Made of cellulose - structure and inter-cellular transportation of nutrients via plasmodesmata.






13. Free energy in reactants stored in products (carbs)






14. Made of amino acids - structure (ex. cytoskeleton) - produce enzymes






15. Fuel - paper - construction materials - furniture - latex - resins - syrup






16. Synthesize proteins based on mRNA code






17. General purpose cell. thin primary cell wall. most common






18. Haploid - produces gametes through mitosis






19. Proteins - lipids - carbohydrates - and nucleic acid






20. Indeterminate growth - assisted reproduction - protection (chemical deterence - spikes - internal resource transport)






21. Stores water and waste and ultimately determines the shape of the cell






22. Lengthen roots and stem - produce xylem and phloem - ground tissue - and epidermis






23. Attach themselves to other plants and suck nutrients out of the air (fog - humidity)






24. Anchor the plant - collect water and nutrients from the ground






25. Mosses have no vascular tissue. Ferns reproduce with spores. Conifers reproduce with seeds. Flowering plants have flowers.






26. Production of two spore types (gymnosperms and angiosperms)






27. Between cells






28. Special leaves that act as arms that pull up or support the stem






29. Special pointy leaves made to protect the stem






30. Photosynthesis and storage






31. Made of acetyl groups - structure energy and storage






32. Produce vessels year round (ex. northern Arizona aspen)






33. Rigid support - mostly found in bark. two types -- fibers and sclereids






34. Flower to play the role of the gametophyte - producing two different spore types






35. The atmosphere is 21% oxygen - so that inherently means that over time plants have taken in more CO2 than they produce. this must be the case - otherwise we would all be dead.


36. The OEC splits water and transfers the electrons to the P680 or cholorphyll reaction center. In the meantime - the photosystem is absorbing light energy and funnels the energy into the p680 - from which - through a series of redox reactions - the kin






37. Spore that gives rise to independent bisexual gametophyte that produces both egg and sperm (mosses and ferns)






38. Through cells






39. Addition of H2O to break apart polymer






40. A thin membrane around the cytoplasm of a cell - gatekeeper of the cell






41. Part of calvin cycle where ATP and NADH are created






42. CO2 (exhale) + H20 + ATP (energy) ? CH20 (food) + 02 (air)






43. Change root structure entirely - make little bubble roots to help acquire nitrogen and phosphorous in exchange for sugars






44. Cytoskeleton -- motor proteins carry molecules and organelles across microtubule tracks






45. Diploid - produces spores through meiosis






46. Makes dermal tissue for bark






47. Position reactants so they dont require as much activation energy






48. 1. Prokaryotes are approximately the same size as their organelle counterparts. 2. Double membrane 3. Chloroplasts and mitochondria have their own unique circular DNA






49. Stick straight up and act like straws in swamp and mangrove plants






50. First step in releasing the energy of glucose - in which a molecule of glucose is broken into two molecules of pyruvic acid
