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






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






3. Convert light energy to chemical energy






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






5. Provides flexible support - like in celery






6. Sorting and shipping of molecules






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






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






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






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






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






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






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






14. Part of leaf for photosynthesis






15. Through cells






16. Produces secondary vascular tissue






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






18. Glycolysis - krebs cycle - electron transport chain






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






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






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






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






23. Provide oxygen - food - medicine - fuel - shelter - paper products - beauty






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






25. Between cells






26. Penetrate root cortex into vascular tissue - aid in acquiring nitrogen and phosphorous in exchange for sugars






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






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






29. Removal of H2O to link monomer and polymers






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






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






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






33. 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






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






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






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






37. Diploid - produces spores through meiosis






38. Attached directly by the base






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






40. Haploid - produces gametes through mitosis






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






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






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






44. Makes dermal tissue for bark






45. Increase population fitness in unstable environments






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






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






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






49. CO2 - H2O - NADH - (ATP)






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