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






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






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






4. Convert carbs into ATP






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






6. Fuel - paper - construction materials - furniture - latex - resins - syrup






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






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






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






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






11. Proteins - lipids - carbohydrates - and nucleic acid






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






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






14. 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.


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






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






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






18. Between cells






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






20. Outer layer - barrier to animals and pathogens






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






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






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






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






25. ***lets them be sexual?






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






27. Made of acetyl groups - structure energy and storage






28. Command center






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






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






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






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






33. CO2 - H2O - NADH - (ATP)






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






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






36. Provides flexible support - like in celery






37. Synthesize proteins based on mRNA code






38. Penetrate root cortex into vascular tissue - aid in acquiring nitrogen and phosphorous in exchange for sugars






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






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






41. Photosynthesis and storage






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






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






44. Convert light energy to chemical energy






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






46. Makes dermal tissue for bark






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






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






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






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