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. The process by which a cell becomes specialized for a specific structure or function






2. Produces and stores nutrients through photosynthesis






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






4. Group of similarly constructed cells that perform the same function within a multicellular organism






5. Useful for tearing and scratching






6. The spore - producing individual or phase in the life cycle of a plant having alternation of generations






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






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






9. xylem and phloem; transport fluid and nutrients internally






10. An extensive membrane network of cisternae (sac - like structures) held together by the cytoskeleton that encloses the cisternal space (or lumen) from the cytosol and is continuous with the perinuclear space. Three types: RER - SER - SR






11. The basic structural and functional unit of all organisms






12. A cell that can differentiate into many different cell types






13. Structure within a cell that is responsible for a specific function






14. Connective - muscle - nervous - epithelial






15. Last stage of mitosis - in which the cell membrane begins to pinch the cell in two - cytokinesis begins - and the nuclear membrane forms around the chromosomes






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






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






18. Obsolete taxonomic group containing bacteria and cyanobacteria






19. In plants - a form of undifferentiated embryonic cell; exists in areas of plant growth like the root and shoot tips






20. The gamete - producing individual or phase in the life cycle of a plant having alternation of generations






21. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






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






23. One of two identical 'sister' parts of a duplicated chromosome






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






25. Division of the cytoplasm during cell division






26. Brain and spinal cord






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






28. Largest organ in terms of surface area






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






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






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






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






33. Discovered mitosis






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






35. Produce progesterone and estrogens - in addition to eggs






36. So named because it lacks striations. Involuntary muscle found along the walls of the digestive tract - bladder - arteries - and other internal organs.






37. Organelle in which proteins are synthesized






38. Is actually a lymphoid organ in the neck or upper chest of all vertebrates. It is essential in the normal development of the immune system.






39. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






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






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






42. 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.






43. Stores and releases bile






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






45. Region of condense chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis.






46. Stores solid waste products






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






48. Produces digestive enzymes and the hormones insulin and glucagons






49. Produce testosterone and sperm






50. Organelle containing genetic material
