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






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






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






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






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






6. Proteins - lipids - carbohydrates - and nucleic acid






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






8. Convert carbs into ATP






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






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






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






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






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






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






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






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






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






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






19. Produces secondary vascular tissue






20. Ability crucial to plant structure and processing of energy - allows change to be made to help survival






21. Part of leaf for photosynthesis






22. Command center






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






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






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






26. Between cells






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






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






29. Outer layer - barrier to animals and pathogens






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






31. Through cells






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






33. Haploid - produces gametes through mitosis






34. Addition of H2O to break apart polymer






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






36. Large compound formed from combinations of many monomers






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






38. CO2 - H2O - NADH - (ATP)






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






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






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






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






43. Attached directly by the base






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






45. Diploid - produces spores through meiosis






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






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






48. Removal of H2O to link monomer and polymers






49. Synthesize proteins based on mRNA code






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