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






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






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






4. Large compound formed from combinations of many monomers






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






6. Makes dermal tissue for bark






7. Allows plants to combat sessileness and control growth and allocate resources effectively to best compete/survive in their environment via meristems






8. Attached directly by the base






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






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






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






12. Part of leaf for photosynthesis






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






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






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






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






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






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






19. Produces secondary vascular tissue






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






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






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






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






24. Mycorrhizas and the bubble shaped guys






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






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






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






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






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






30. Have underground stems that store starch (ex. potato)






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






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






33. Increase population fitness in unstable environments






34. Addition of H2O to break apart polymer






35. Proteins - lipids - carbohydrates - and nucleic acid






36. Glycolysis - krebs cycle - electron transport chain






37. 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






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






39. Haploid - produces gametes through mitosis






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






41. Produce vessels in spring and tracheids in winter (ex. oak tree)






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






43. Outer layer - barrier to animals and pathogens






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






45. Organic compounds not directly involved in normal growth of organism. Facilitates reproduction and defense against predators.






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






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






48. Removal of H2O to link monomer and polymers






49. 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






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