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






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






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






4. Convert carbs into ATP






5. CO2 - H2O - NADH - (ATP)






6. Addition of H2O to break apart polymer






7. Makes dermal tissue for bark






8. Command center






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






10. First step in releasing the energy of glucose - in which a molecule of glucose is broken into two molecules of pyruvic acid






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






12. Convert light energy to chemical energy






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






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






15. Sorting and shipping of molecules






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






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






18. Glycolysis - krebs cycle - electron transport chain






19. Synthesize proteins based on mRNA code






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






21. Special pointy leaves made to protect the stem






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






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






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






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






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






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






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






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






30. 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.

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






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






33. Through cells






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






35. Photosynthesis and storage






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






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






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






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






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






41. Between cells






42. When xylem is blocked by air bubbles as a result of gasses clotting together after freeze-thaw cycles or extreme water-tension






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






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






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






46. Large compound formed from combinations of many monomers






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






48. Mycorrhizas and the bubble shaped guys






49. Proteins - lipids - carbohydrates - and nucleic acid






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