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. Convert light energy to chemical energy






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






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






5. Removal of H2O to link monomer and polymers






6. 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.

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






8. Diploid - produces spores through meiosis






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






10. Makes dermal tissue for bark






11. ***lets them be sexual?






12. Sorting and shipping of molecules






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






14. Proteins - lipids - carbohydrates - and nucleic acid






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






16. Free energy in reactants stored in products (carbs)






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






18. Addition of H2O to break apart polymer






19. Photosynthesis and storage






20. Part of leaf for photosynthesis






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






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






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






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






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






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






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






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






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






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






31. Mycorrhizas and the bubble shaped guys






32. Between cells






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






34. Large compound formed from combinations of many monomers






35. Increase population fitness in unstable environments






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






37. Synthesize proteins based on mRNA code






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






39. CO2 - H2O - NADH - (ATP)






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






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






42. 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






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






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






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






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






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






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






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






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