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






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






3. Increase population fitness in unstable environments






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






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






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






7. Mycorrhizas and the bubble shaped guys






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






9. Haploid - produces gametes through mitosis






10. Part of leaf for photosynthesis






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






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






13. Makes dermal tissue for bark






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






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






16. 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






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






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






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






20. Large compound formed from combinations of many monomers






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






22. Addition of H2O to break apart polymer






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






24. Photosynthesis and storage






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






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






27. Root hairs capture water and minerals and move them through (symplasticly) or between (apoplasticly) cells until the endodermis filters it into the vascular tissue






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






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






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






31. Brings leaf water and nutrients - exports sugars






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






33. Proteins - lipids - carbohydrates - and nucleic acid






34. Alternate between sporophyte and gametophyte in the plant life cycle






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






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






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






38. Produces secondary vascular tissue






39. Removal of H2O to link monomer and polymers






40. Through cells






41. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






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






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






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






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






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






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






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






49. Provides flexible support - like in celery






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