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






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






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






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






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






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






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






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






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






10. 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.

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






12. Outer layer - barrier to animals and pathogens






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






14. Have underground stems that store starch (ex. potato)






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






16. Increase population fitness in unstable environments






17. Attached directly by the base






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






19. Produces secondary vascular tissue






20. Sorting and shipping of molecules






21. Glycolysis - krebs cycle - electron transport chain






22. Through cells






23. 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






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






25. Removal of H2O to link monomer and polymers






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






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






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






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






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






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






32. Command center






33. ***lets them be sexual?






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






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






36. Special pointy leaves made to protect the stem






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






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






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






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






41. Root apical meristem (quiescent center - or zone of cell division) - zone of elongation - zone of maturation






42. Brings leaf water and nutrients - exports sugars






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






44. Made of acetyl groups - structure energy and storage






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






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






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






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






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






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