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






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






3. ***lets them be sexual?






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






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






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






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






8. Outer layer - barrier to animals and pathogens






9. Gather and convert light energy - control CO2 and water loss






10. Synthesize proteins based on mRNA code






11. CO2 - H2O - NADH - (ATP)






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






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






14. Removal of H2O to link monomer and polymers






15. Between cells






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






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






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






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






20. 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






21. Command center






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






23. Addition of H2O to break apart polymer






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






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






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






27. Photosynthesis and storage






28. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






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






34. 1. Prokaryotes are approximately the same size as their organelle counterparts. 2. Double membrane 3. Chloroplasts and mitochondria have their own unique circular DNA






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






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






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






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






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






40. Convert light energy to chemical energy






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






42. Produces secondary vascular tissue






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






44. 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.


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






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






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






48. Diploid - produces spores through meiosis






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






50. Brings leaf water and nutrients - exports sugars
