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






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






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






4. Photosynthesis and storage






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






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






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






8. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






12. Convert light energy to chemical energy






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






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






15. Addition of H2O to break apart polymer






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






17. Through cells






18. Produces secondary vascular tissue






19. Between cells






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






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






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






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






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






25. Glycolysis - krebs cycle - electron transport chain






26. Sorting and shipping of molecules






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






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






29. Biological fuel. captured and stored through photosynthesis - extracted by mitochondria






30. Change root structure entirely - make little bubble roots to help acquire nitrogen and phosphorous in exchange for sugars






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






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






33. Outer layer - barrier to animals and pathogens






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






35. CO2 - H2O - NADH - (ATP)






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






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






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






39. Synthesize proteins based on mRNA code






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






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






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






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






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






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






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






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






48. 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






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






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