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. All of the nerves leading to and from the central nervous system






2. A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote






3. 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.






4. Attaches to bones and is responsible for voluntary movements






5. Plant with specialized tissue for conducting water and nutrients






6. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






7. Protects the body and holds in heat






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






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






10. Division of the cytoplasm during cell division






11. xylem and phloem; transport fluid and nutrients internally






12. Organelle containing genetic material






13. Obsolete taxonomic group containing bacteria and cyanobacteria






14. Detoxifies the blood - produces bile - and stores many vitamins and minerals






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






16. Organelle in which proteins are synthesized






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






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






19. Include macrophages - B- cells - and T- cells






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






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






22. Third phase of mitosis and of meiosis I and II - in which the sister chromatids separate and move toward the poles of the spindle






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






24. 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






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






26. Connective - muscle - nervous - epithelial






27. 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.






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






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






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






31. Produce testosterone and sperm






32. Discovered meiosis






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






34. Contracts or shortens making body parts move






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






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






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






38. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






39. Stores solid waste products






40. Largest organ in terms of surface area






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






42. Epidermis - vascular - ground






43. Made up of celluolose - protein - and lignin - and allows pressure in plant cells to increase without the cell bursting.






44. Stores and releases bile






45. Discovered mitosis






46. Tiny nodules found all over the body. They contain a colorless fluid called lymph.






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






48. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






49. Process that results in cell division to produce gametes






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