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






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






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






4. Large compound formed from combinations of many monomers






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






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






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






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






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






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






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






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






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






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






15. CO2 (exhale) + H20 + ATP (energy) ? CH20 (food) + 02 (air)






16. 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






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






18. Increase population fitness in unstable environments






19. Makes dermal tissue for bark






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






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






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






23. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.






24. Convert light energy to chemical energy






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






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






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






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






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






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






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






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






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






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






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






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






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






38. Addition of H2O to break apart polymer






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






40. Between cells






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






42. Provides flexible support - like in celery






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






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






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






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






47. Proteins - lipids - carbohydrates - and nucleic acid






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






49. Haploid - produces gametes through mitosis






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