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. Addition of H2O to break apart polymer






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






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






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






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






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






8. Proteins - lipids - carbohydrates - and nucleic acid






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






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






11. Waxy protection of leaf to protect from pathogens and let water run off it






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






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






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






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






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






17. Glycolysis - krebs cycle - electron transport chain






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






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






20. Attached directly by the base






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






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






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






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






25. Through cells






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






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






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






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






30. Part of leaf for photosynthesis






31. Photosynthesis and storage






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






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






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






35. Command center






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






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






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






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






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






41. Special pointy leaves made to protect the stem






42. Provides flexible support - like in celery






43. Haploid - produces gametes through mitosis






44. Large compound formed from combinations of many monomers






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






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






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






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






49. CO2 - H2O - NADH - (ATP)






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