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. Diploid - produces spores through meiosis






2. Convert carbs into ATP






3. Outer layer - barrier to animals and pathogens






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






5. 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.

6. Made of acetyl groups - structure energy and storage






7. Brings leaf water and nutrients - exports sugars






8. Synthesize proteins based on mRNA code






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






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






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






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






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






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






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






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






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






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






19. Haploid - produces gametes through mitosis






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






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






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






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






24. Large compound formed from combinations of many monomers






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






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






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






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






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






30. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars. 1)reduction - 2)carbon fixation - 3)regeneration






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






32. Through cells






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






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






35. Removal of H2O to link monomer and polymers






36. Glycolysis - krebs cycle - electron transport chain






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






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






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






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






41. Provides flexible support - like in celery






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






43. Command center






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






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






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






47. CO2 - H2O - NADH - (ATP)






48. Mycorrhizas and the bubble shaped guys






49. Photosynthesis and storage






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