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. Photosynthesis and storage






3. Made of acetyl groups - structure energy and storage






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






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






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






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






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






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






10. Synthesize proteins based on mRNA code






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






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






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






14. Mycorrhizas and the bubble shaped guys






15. Makes dermal tissue for bark






16. Convert light energy to chemical energy






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






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






19. Haploid - produces gametes through mitosis






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






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






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






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






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






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






26. ***lets them be sexual?






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






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






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






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






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






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






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






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






35. Special pointy leaves made to protect the stem






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






37. Increase population fitness in unstable environments






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






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






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






41. Command center






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






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






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






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






46. CO2 - H2O - NADH - (ATP)






47. Between cells






48. Produces secondary vascular tissue






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






50. Glycolysis - krebs cycle - electron transport chain
