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. 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






2. Holds tissues together






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






4. Organelle in which calcium levels are regulated






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






6. Produces digestive enzymes and the hormones insulin and glucagons






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






8. Stores solid waste products






9. Discovered mitosis






10. Stores and releases bile






11. 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






12. Division of the cytoplasm during cell division






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






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






15. Produce progesterone and estrogens - in addition to eggs






16. 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.






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






18. Largest organ in terms of surface area






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






20. Small sac within a cell formed by pinching of some membrane; can contain waste - products the cell is taking in - and secretions the cell is exporting






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






22. Connective - muscle - nervous - epithelial






23. Contracts or shortens making body parts move






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






25. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.






26. Process that results in cell division to produce gametes






27. Attaches to bones and is responsible for voluntary movements






28. 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.






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






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






31. 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






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






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






34. Any cell in a multicellular organism except the gametes






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






36. Release of water from plants through stomata






37. Organelle containing genetic material






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






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






40. 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






41. Useful for tearing and scratching






42. Nutrient conducting plant tissue; formed like small tubules; living cells






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






44. Discovered meiosis






45. Membrane - bound and fluid filled organelle in plant of fungal cells; also found in some bacterial - protist - and animal cells






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






47. Involuntary muscle that forms the contractile walls of the heart






48. Produce testosterone and sperm






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






50. Responsible for digesting and absorbing the extracted vital nutrients from food
