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. Through cells






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






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






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






5. Glycolysis - krebs cycle - electron transport chain






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






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






8. Web of protein strands throughout the cell that allows organelles and molecules to move via motor proteins






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






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






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






12. Sorting and shipping of molecules






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






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






15. Diploid - produces spores through meiosis






16. Increase population fitness in unstable environments






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






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






19. Brings leaf water and nutrients - exports sugars






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






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






22. ***lets them be sexual?






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






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






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






26. 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






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






28. Removal of H2O to link monomer and polymers






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






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






31. Command center






32. Addition of H2O to break apart polymer






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






34. Haploid - produces gametes through mitosis






35. Large compound formed from combinations of many monomers






36. Part of leaf for photosynthesis






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






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






39. Provides flexible support - like in celery






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






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






42. Made of amino acids - structure (ex. cytoskeleton) - produce enzymes






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






44. Mycorrhizas and the bubble shaped guys






45. 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.

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






47. Attached directly by the base






48. Proteins - lipids - carbohydrates - and nucleic acid






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






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