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






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






3. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






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






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






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






12. Photosynthesis and storage






13. Glycolysis - krebs cycle - electron transport chain






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






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






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






17. Convert light energy to chemical energy






18. Increase population fitness in unstable environments






19. Makes dermal tissue for bark






20. Make long thin stems called 'runners' that grow above ground and aid in asexual reproduction






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






22. Provides flexible support - like in celery






23. Convert carbs into ATP






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






25. Between cells






26. Produces secondary vascular tissue






27. 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






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






29. Synthesize proteins based on mRNA code






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






31. Haploid - produces gametes through mitosis






32. Addition of H2O to break apart polymer






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






34. Through cells






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






36. CO2 - H2O - NADH - (ATP)






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






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






39. Proteins - lipids - carbohydrates - and nucleic acid






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. Command center






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






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






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






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






46. Sorting and shipping of molecules






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






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






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






50. Mycorrhizas and the bubble shaped guys
