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. Diploid - produces spores through meiosis






2. Through cells






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






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






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






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






7. Removal of H2O to link monomer and polymers






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






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






10. Outer layer - barrier to animals and pathogens






11. Produces microgametophyte that stays with sporophyte plant (produces egg)






12. Sorting and shipping of molecules






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






14. Gather and convert light energy - control CO2 and water loss






15. Produces secondary vascular tissue






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






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






18. Mycorrhizas and the bubble shaped guys






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






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






21. Addition of H2O to break apart polymer






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






23. ***lets them be sexual?






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






25. Photosynthesis and storage






26. Makes dermal tissue for bark






27. Haploid - produces gametes through mitosis






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






29. Special pointy leaves made to protect the stem






30. Increase population fitness in unstable environments






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






32. 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.

33. CO2 - H2O - NADH - (ATP)






34. Proteins - lipids - carbohydrates - and nucleic acid






35. Synthesize proteins based on mRNA code






36. Glycolysis - krebs cycle - electron transport chain






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






38. Provides flexible support - like in celery






39. Command center






40. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars. 1)reduction - 2)carbon fixation - 3)regeneration






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






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






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






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






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






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






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






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






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






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