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. Inter-cellular links for long distance transportation of nutrients






2. Increase population fitness in unstable environments






3. Between cells






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






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






6. Stores water and waste and ultimately determines the shape of the cell






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






8. Diploid - produces spores through meiosis






9. First step in releasing the energy of glucose - in which a molecule of glucose is broken into two molecules of pyruvic acid






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






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






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






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






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






15. Special pointy leaves made to protect the stem






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






17. Part of leaf for photosynthesis






18. Addition of H2O to break apart polymer






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






20. Free energy plants get out of the reactant's potential energy






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






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






23. Synthesize proteins based on mRNA code






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






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






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






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






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






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






30. Proteins - lipids - carbohydrates - and nucleic acid






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






32. CO2 - H2O - NADH - (ATP)






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






35. 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






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






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






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






39. Provides flexible support - like in celery






40. Through cells






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






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






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






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






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






46. Made of acetyl groups - structure energy and storage






47. Haploid - produces gametes through mitosis






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






49. Large compound formed from combinations of many monomers






50. Produces secondary vascular tissue
