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. Release of water from plants through stomata






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






3. Plant with specialized tissue for conducting water and nutrients






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






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






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






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






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






9. Largest organ in terms of surface area






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






11. Produces and stores nutrients through photosynthesis






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






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






14. 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.






15. Organelle in which calcium levels are regulated






16. Organelle containing genetic material






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






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






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






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






21. Discovered mitosis






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






23. Useful for tearing and scratching






24. Brain and spinal cord






25. Stores solid waste products






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






27. Organelle containing enzymes used in cell digestion






28. Protects the body and holds in heat






29. Connective - muscle - nervous - epithelial






30. 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






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






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






34. xylem and phloem; transport fluid and nutrients internally






35. Produce testosterone and sperm






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






37. Sweat glands and sebaceous glands






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






39. Any cell in a multicellular organism except the gametes






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






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






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






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






44. Organelle in which proteins are synthesized






45. Process that results in cell division to produce gametes






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






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






48. 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






49. Produce progesterone and estrogens - in addition to eggs






50. Cells that form the outer surface of plants
