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. Brings leaf water and nutrients - exports sugars






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






3. Diploid - produces spores through meiosis






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






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






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






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






8. Mycorrhizas and the bubble shaped guys






9. Glycolysis - krebs cycle - electron transport chain






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






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






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






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






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






15. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






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






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






22. Increase population fitness in unstable environments






23. Between cells






24. 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






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






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






27. Organic molecules (materials) - enzymes (workers) - DNA (blueprint)






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






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






30. Makes dermal tissue for bark






31. Outer layer - barrier to animals and pathogens






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






33. Produces secondary vascular tissue






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






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






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






37. Convert carbs into ATP






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






39. Part of leaf for photosynthesis






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






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






42. Photosynthesis and storage






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






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






45. Removal of H2O to link monomer and polymers






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






47. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars. 1)reduction - 2)carbon fixation - 3)regeneration






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






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






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