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






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






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






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






5. Inter-cellular links for long distance transportation of nutrients






6. Produces megagametophyte that stays with sporophyte plant (produces egg)






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






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






9. Large compound formed from combinations of many monomers






10. Makes dermal tissue for bark






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






12. ***lets them be sexual?






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






14. Command center






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






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






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






18. Produces secondary vascular tissue






19. Addition of H2O to break apart polymer






20. 1) taking wood from an ecosystem also takes nutrients 2) seedling establishment isn't that easy -- lots of competition and herbivory to overcome in building a new forest






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






22. Second stage of cellular respiration - in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions






23. Haploid - produces gametes through mitosis






24. Proteins - lipids - carbohydrates - and nucleic acid






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






26. Provide oxygen - food - medicine - fuel - shelter - paper products - beauty






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






28. Removal of H2O to link monomer and polymers






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






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






31. Mycorrhizas and the bubble shaped guys






32. Provides flexible support - like in celery






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






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. 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






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






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






38. Synthesize proteins based on mRNA code






39. Free energy plants get out of the reactant's potential energy






40. Outer layer - barrier to animals and pathogens






41. Made of acetyl groups - structure energy and storage






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






43. Molecule manufacturing where ribosomes are - and then products are sent to the Golgi Apparatus






44. Brings leaf water and nutrients - exports sugars






45. CO2 - H2O - NADH - (ATP)






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






47. Part of leaf that is loose for easy gas diffusion






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. Production of two spore types (gymnosperms and angiosperms)






50. Alternate between sporophyte and gametophyte in the plant life cycle
