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 digesting and absorbing the extracted vital nutrients from food






2. Stores and releases bile






3. Produce progesterone and estrogens - in addition to eggs






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






5. Produce testosterone and sperm






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






7. 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.






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






9. Stage of mitosis in which chromosomes condense into structures visible in a regular microscope






10. Contracts or shortens making body parts move






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






12. 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.






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






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






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






16. Process that results in cell division to produce gametes






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






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






19. Largest organ in terms of surface area






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






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






22. Organelle containing genetic material






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






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






25. Cells that form the outer surface of plants






26. The basic structural and functional unit of all organisms






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






28. 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






29. 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






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






31. Discovered meiosis






32. Discovered mitosis






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






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






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






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






37. xylem and phloem; transport fluid and nutrients internally






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






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






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






41. Plant with specialized tissue for conducting water and nutrients






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






43. Obsolete taxonomic group containing bacteria and cyanobacteria






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






45. Sweat glands and sebaceous glands






46. Useful for tearing and scratching






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






48. 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






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






50. Release of water from plants through stomata
