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. Sorting and shipping of molecules






2. Addition of H2O to break apart polymer






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






4. Through cells






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






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






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






8. Photosynthesis and storage






9. A series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP by redox reactions






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






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






12. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






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






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






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






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






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






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






23. CO2 - H2O - NADH - (ATP)






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






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






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






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






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






29. Synthesize proteins based on mRNA code






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






31. 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.


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






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






34. Haploid - produces gametes through mitosis






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






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






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






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






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






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






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






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






43. Made of acetyl groups - structure energy and storage






44. Large compound formed from combinations of many monomers






45. Makes dermal tissue for bark






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






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






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






49. ***lets them be sexual?






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