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. Sorting and shipping of molecules






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






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






4. Convert carbs into ATP






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






6. Position reactants so they dont require as much activation energy






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






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






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






10. ***lets them be sexual?






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






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






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






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






15. Cytoskeleton -- motor proteins carry molecules and organelles across microtubule tracks






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






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






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






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






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






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






22. Inter-cellular links for long distance transportation of nutrients






23. Made of acetyl groups - structure energy and storage






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






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






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






27. Proteins - lipids - carbohydrates - and nucleic acid






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






29. Special pointy leaves made to protect the stem






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






31. Through cells






32. Makes dermal tissue for bark






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






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






35. Command center






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






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






38. Removal of H2O to link monomer and polymers






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






40. Outer layer - barrier to animals and pathogens






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






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






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






44. Synthesize proteins based on mRNA code






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






46. Large compound formed from combinations of many monomers






47. Attached directly by the base






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






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






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