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 ATP and NADH are created






2. Synthesize proteins based on mRNA code






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






25. 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






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






27. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






28. Removal of H2O to link monomer and polymers






29. Makes dermal tissue for bark






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






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






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






33. Comes in twos - sieve tubes (no nucleus) and companion cells (nourish sieve tubes) - transport sugars and nutrients






34. ***lets them be sexual?






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






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






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






38. Made of acetyl groups - structure energy and storage






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






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






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






42. Sorting and shipping of molecules






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






44. Diploid - produces spores through meiosis






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






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






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






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






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






50. Increase population fitness in unstable environments
