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






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






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






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






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






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






7. Convert light energy to chemical energy






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






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






10. CO2 (air) + H20 (soil) + light energy (sun) ? CH20 (carbs) + 02 (oxygen)






11. Photosynthesis and storage






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






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






14. Synthesize proteins based on mRNA code






15. Through cells






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






17. Increase population fitness in unstable environments






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






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






20. Large compound formed from combinations of many monomers






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






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






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






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






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






26. Sorting and shipping of molecules






27. Alternate between sporophyte and gametophyte in the plant life cycle






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






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






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






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






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






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






34. Provide oxygen - food - medicine - fuel - shelter - paper products - beauty






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






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






37. 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.


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






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






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






41. Outer layer - barrier to animals and pathogens






42. Attached directly by the base






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






44. Diploid - produces spores through meiosis






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






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






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






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






49. Haploid - produces gametes through mitosis






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