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






3. 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.

4. Attached directly by the base






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






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






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






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






9. Part of leaf for photosynthesis






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






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






12. Between cells






13. Haploid - produces gametes through mitosis






14. Proteins - lipids - carbohydrates - and nucleic acid






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






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






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






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






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






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






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






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






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






24. Made of acetyl groups - structure energy and storage






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






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






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






28. The OEC splits water and transfers the electrons to the P680 or cholorphyll reaction center. In the meantime - the photosystem is absorbing light energy and funnels the energy into the p680 - from which - through a series of redox reactions - the kin






29. Develop bordered pits to prevent spreading of bubbles - tracheids let water move laterally - refill at night - produce new xylem every spring






30. Brings leaf water and nutrients - exports sugars






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






32. Sorting and shipping of molecules






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






34. ***lets them be sexual?






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






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






37. Addition of H2O to break apart polymer






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






39. Synthesize proteins based on mRNA code






40. 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






41. Provides flexible support - like in celery






42. Photosynthesis and storage






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






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






45. Makes dermal tissue for bark






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






47. Convert carbs into ATP






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






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






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