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. Connective - muscle - nervous - epithelial






2. Organelle containing enzymes used in cell digestion






3. Stores and releases bile






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






5. Supportive layer of tissue (sapwood or heartwood in trees) that carries water and nutrients up from the roots; dead cells






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






7. Produce testosterone and sperm






8. The basic structural and functional unit of all organisms






9. Stores solid waste products






10. 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






11. Division of the cytoplasm during cell division






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






13. 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






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






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






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






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






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






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






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






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






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






23. Useful for tearing and scratching






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






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






26. Produces and stores nutrients through photosynthesis






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






28. Largest organ in terms of surface area






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






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






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






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






33. Discovered meiosis






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






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






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






37. Organelle containing genetic material






38. Protects the body and holds in heat






39. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






44. Process that results in cell division






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






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






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






48. Organelle in which calcium levels are regulated






49. Produce progesterone and estrogens - in addition to eggs






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