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






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






3. Eukaryotic organism that is not an animal - a plant - or a fungus.






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






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






6. 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






7. Useful for tearing and scratching






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






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






10. 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






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






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






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






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






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






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






17. Produces digestive enzymes and the hormones insulin and glucagons






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






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






20. Stores and releases bile






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






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






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






24. xylem and phloem; transport fluid and nutrients internally






25. In the life cycle of a plant or alga undergoing alternation of generations - a meiotically produced haploid cell that divides mitotically - generating a multicellular individual - the gametophyte - without fusing with another cell.






26. Organelle containing enzymes used in cell digestion






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






28. Any cell in a multicellular organism except the gametes






29. Protects the body and holds in heat






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






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






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






33. Organelle in which calcium levels are regulated






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






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






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






37. Epidermis - vascular - ground






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






39. Organelle containing genetic material






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






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






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






43. Sweat glands and sebaceous glands






44. Brain and spinal cord






45. 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.






46. 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






47. Division of the cytoplasm during cell division






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






49. Produces and stores nutrients through photosynthesis






50. Attaches to bones and is responsible for voluntary movements
