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






2. Part of leaf for photosynthesis






3. Produces bisexual spores - they become gametophytes w/ egg and sperm (study the picture)






4. Outer layer - barrier to animals and pathogens






5. CO2 - H2O - NADH - (ATP)






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






7. 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






8. ***lets them be sexual?






9. Proteins - lipids - carbohydrates - and nucleic acid






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






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






12. 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.

13. 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






14. Provides flexible support - like in celery






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






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






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






18. Between cells






19. Through cells






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






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






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






23. Large compound formed from combinations of many monomers






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






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






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






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






28. Diploid - produces spores through meiosis






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






30. Removal of H2O to link monomer and polymers






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






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






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






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






35. Makes dermal tissue for bark






36. Synthesize proteins based on mRNA code






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






38. Convert light energy to chemical energy






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






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






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






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






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






44. Command center






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






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






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






48. Convert carbs into ATP






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






50. Mycorrhizas and the bubble shaped guys
