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






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






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






4. Increase population fitness in unstable environments






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






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






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






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






9. Synthesize proteins based on mRNA code






10. Between cells






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






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






13. Through cells






14. Convert carbs into ATP






15. Addition of H2O to break apart polymer






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






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






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






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






20. Number of ATP molecules from 1 glucose in cellular respiration (total produced -- 38 - total yield -- 36)






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






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






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






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






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






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






27. Photosynthesis and storage






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






29. Sorting and shipping of molecules






30. Outer layer - barrier to animals and pathogens






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






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






33. CO2 - H2O - NADH - (ATP)






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






35. Made of acetyl groups - structure energy and storage






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






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






38. Makes dermal tissue for bark






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






40. 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






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






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






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






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






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






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






47. Produces secondary vascular tissue






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






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






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