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






2. Convert light energy to chemical energy






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






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






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






6. ***lets them be sexual?






7. Brings leaf water and nutrients - exports sugars






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






9. Removal of H2O to link monomer and polymers






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






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






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






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






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






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






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






17. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






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






19. Attached directly by the base






20. Special pointy leaves made to protect the stem






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






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






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






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






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






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






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






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






31. Between cells






32. Haploid - produces gametes through mitosis






33. 1. Prokaryotes are approximately the same size as their organelle counterparts. 2. Double membrane 3. Chloroplasts and mitochondria have their own unique circular DNA






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






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






36. Part of leaf for photosynthesis






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






38. Increase population fitness in unstable environments






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






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






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






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






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






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






45. The atmosphere is 21% oxygen - so that inherently means that over time plants have taken in more CO2 than they produce. this must be the case - otherwise we would all be dead.

46. Photosynthesis and storage






47. Sorting and shipping of molecules






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






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






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