CSET Science: Subtest I Cell And Organismal Biology

Subjects : cset, 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. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






2. Thin layer of plant tissue just below the bark which produces the xylem






3. Plants with no phloem - xylem - roots - stems - or leaves; not as large or intricate as vascular plants






4. Organelle in which proteins are synthesized






5. Process that results in cell division






6. Attaches to bones and is responsible for voluntary movements






7. Located in the neck area. Releases thyroxin - which regulates the body's metabolic rate.






8. Cells that are able to differentiate into any type of cell in an organism






9. Responsible for defending the body against disease - causing agents; white blood cells (macrophages - B- cells and T- cells) - lymph nodes






10. Continuous sequence of growth (interphase) and division (mitosis) in a cell






11. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






12. Plant with specialized tissue for conducting water and nutrients






13. Microtubule within a cell's nucleus; joined to one of the poles during cell division






14. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






15. Division of the cytoplasm during cell division






16. Epidermis - vascular - ground






17. Responsible for the collection - transference - and the processing of external and internal information throughout the body; central nervous system - peripheral nervous system






18. Obsolete taxonomic group containing bacteria and cyanobacteria






19. Release of water from plants through stomata






20. Connections between plant cells that allow fluids and nutrients to be shared






21. Holds tissues together






22. Discovered meiosis






23. Responsible for storing food and initiating the digestion of proteins






24. Stores solid waste products






25. Organelles critical to protein synthesis found in the cytoplasm - joined to the endoplasmic reticulum - and within the mitochondria






26. Organisms with cells that lack membranous - structurally discrete organelles






27. One of the cells formed from a parents cell after mitosis






28. Pores underneath plant leaves used to exchange carbon dioxide and oxygen






29. Responsible for transporting materials throughout the body: heart - blood (red - white - platelets) - blood vessels (arteries - vein - capillaries)






30. A doubled rod of condensed chromatin; contains DNA that carries genetic information.






31. A complex polymer that fills the spaces in the cell wall - conferring mechanical strength to the cell wall and the plant as a whole.






32. Produce progesterone and estrogens - in addition to eggs






33. Strands of plant tissue containing xylem and phloem - sometimes surrounded by a fiber covering






34. Organisms with cells that have a membrane - bound nucleus and other well - structured organelles






35. Produces and stores nutrients through photosynthesis






36. Stage in which chromosomes are aligned in the center of the cell






37. Produce testosterone and sperm






38. Organelle in which lipids and steroids are produced - carbohydrates and steroids are metabolized - and calcium concentration - drug detoxification - and attachment of cell membrane receptors are regulated.






39. Responsible for releasing several tropic hormones - which regulate the activity of other endocrine glands






40. Protects the body and holds in heat






41. Responsible for providing voluntary and involuntary movement; cardiac - skeletal - smooth






42. Produces digestive enzymes and the hormones insulin and glucagons






43. Responsible for extracting water and essential vitamins from the digested food






44. Organelle that 'packages' proteins to be secreted from the cell






45. Chlorophyll containing plant cell organelle within which photosynthesis takes place






46. Largest organ in terms of surface area






47. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






48. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






49. Ability of a cell to differentiate into multiple different types of cells






50. Organism that harnesses light energy to produce organic materials from carbon dioxide and water
