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






2. Convert light energy to chemical energy






3. Large compound formed from combinations of many monomers






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






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






6. Photosynthesis and storage






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






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






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






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






11. Brings leaf water and nutrients - exports sugars






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






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






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






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






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






17. Outer layer - barrier to animals and pathogens






18. ***lets them be sexual?






19. Haploid - produces gametes through mitosis






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






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






22. Produces secondary vascular tissue






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






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






25. Attach themselves to other plants and suck nutrients out of the air (fog - humidity)






26. Removal of H2O to link monomer and polymers






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






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






29. The OEC splits water and transfers the electrons to the P680 or cholorphyll reaction center. In the meantime - the photosystem is absorbing light energy and funnels the energy into the p680 - from which - through a series of redox reactions - the kin






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






31. CO2 - H2O - NADH - (ATP)






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






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






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






35. Synthesize proteins based on mRNA code






36. Makes dermal tissue for bark






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






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






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






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






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






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






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






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






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






46. Through cells






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






48. Attached directly by the base






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






50. Provides flexible support - like in celery
