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






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






3. Addition of H2O to break apart polymer






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






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






6. Produces secondary vascular tissue






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






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






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






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






11. Through cells






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






13. Made of acetyl groups - structure energy and storage






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






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






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






17. Diploid - produces spores through meiosis






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






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






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






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






22. Synthesize proteins based on mRNA code






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






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






25. Haploid - produces gametes through mitosis






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






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






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






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






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






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






32. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






38. 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






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






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






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






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






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






44. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars. 1)reduction - 2)carbon fixation - 3)regeneration






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






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






47. Increase population fitness in unstable environments






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






49. Proteins - lipids - carbohydrates - and nucleic acid






50. Provides flexible support - like in celery
