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






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






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






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






5. Addition of H2O to break apart polymer






6. Practice of employing management strategies to allow healthy return of timber harvest. (ex. leave mature trees - plant seedlings)






7. Sorting and shipping of molecules






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






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






10. Haploid - produces gametes through mitosis






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






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






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






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






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






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






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






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






19. Large compound formed from combinations of many monomers






20. CO2 - H2O - NADH - (ATP)






21. Diploid - produces spores through meiosis






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






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






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






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






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






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






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






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






30. Makes dermal tissue for bark






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






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






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






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






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






36. Glycolysis - krebs cycle - electron transport chain






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






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






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






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






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






42. Made of acetyl groups - structure energy and storage






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






44. Attached directly by the base






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






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






47. Brings leaf water and nutrients - exports sugars






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






49. 1) taking wood from an ecosystem also takes nutrients 2) seedling establishment isn't that easy -- lots of competition and herbivory to overcome in building a new forest






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