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. Between cells






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






3. Increase population fitness in unstable environments






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






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






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






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






8. Part of calvin cycle where ATP and NADH are created






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






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






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






12. Convert light energy to chemical energy






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






14. Glycolysis - krebs cycle - electron transport chain






15. Makes dermal tissue for bark






16. Attached directly by the base






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






18. Synthesize proteins based on mRNA code






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






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






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






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






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






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






25. Command center






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






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






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






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






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






31. Produces secondary vascular tissue






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






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






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






35. Sorting and shipping of molecules






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






37. Through cells






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






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






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






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






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






43. Diploid - produces spores through meiosis






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






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






46. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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