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. Between cells






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






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






4. Haploid - produces gametes through mitosis






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






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






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






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






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






10. CO2 - H2O - NADH - (ATP)






11. Sorting and shipping of molecules






12. Diploid - produces spores through meiosis






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






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






15. ***lets them be sexual?






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






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






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






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






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






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






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






23. Glycolysis - krebs cycle - electron transport chain






24. Photosynthesis and storage






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






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






27. 1) taking wood from an ecosystem also takes nutrients 2) seedling establishment isn't that easy -- lots of competition and herbivory to overcome in building a new forest






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






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






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






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






32. Made of acetyl groups - structure energy and storage






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






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






35. Produces secondary vascular tissue






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






37. Provides flexible support - like in celery






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






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






40. Proteins - lipids - carbohydrates - and nucleic acid






41. Command center






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






43. Brings leaf water and nutrients - exports sugars






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






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






46. Free energy in reactants stored in products (carbs)






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






48. Convert carbs into ATP






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






50. Special pointy leaves made to protect the stem
