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. Makes dermal tissue for bark






2. Haploid - produces gametes through mitosis






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






4. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






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






6. Attached directly by the base






7. Convert carbs into ATP






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






9. Waxy protection of leaf to protect from pathogens and let water run off it






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






11. CO2 (air) + H20 (soil) + light energy (sun) ? CH20 (carbs) + 02 (oxygen)






12. Provides flexible support - like in celery






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






14. Practice of employing management strategies to allow healthy return of timber harvest. (ex. leave mature trees - plant seedlings)






15. Produce vessels in spring and tracheids in winter (ex. oak tree)






16. Mycorrhizas and the bubble shaped guys






17. 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.

18. Number of ATP molecules from 1 glucose in cellular respiration (total produced -- 38 - total yield -- 36)






19. Brings leaf water and nutrients - exports sugars






20. Diploid - produces spores through meiosis






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






22. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






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






24. Ability crucial to plant structure and processing of energy - allows change to be made to help survival






25. Consists of dead hollowed out cells - come in tracheids (long) or vessels (short) - move water in plant






26. The part of the leaf for protection and gas exchange






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






28. Sorting and shipping of molecules






29. Xylem and phloem - used for transportation of water and sugars in plant






30. Develop bordered pits to prevent spreading of bubbles - tracheids let water move laterally - refill at night - produce new xylem every spring






31. 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






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






33. Produces bisexual spores - they become gametophytes w/ egg and sperm (study the picture)






34. Root hairs capture water and minerals and move them through (symplasticly) or between (apoplasticly) cells until the endodermis filters it into the vascular tissue






35. Photosynthesis and storage






36. Position leaves for max photosynthesis - provide resource transportation and storage - escape herbivores






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






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






39. Large compound formed from combinations of many monomers






40. Command center






41. A series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP by redox reactions






42. Synthesize proteins based on mRNA code






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






44. Allows plants to combat sessileness and control growth and allocate resources effectively to best compete/survive in their environment via meristems






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






46. Organic molecules (materials) - enzymes (workers) - DNA (blueprint)






47. Part of calvin cycle where five G3Ps are recycled - processed - and linked to form more materials for carbon fixation






48. Organic compounds not directly involved in normal growth of organism. Facilitates reproduction and defense against predators.






49. Through cells






50. Addition of H2O to break apart polymer
