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






2. Sweat glands and sebaceous glands






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






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






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






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






7. 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






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






9. 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






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






11. Protects the body and holds in heat






12. Produces digestive enzymes and the hormones insulin and glucagons






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






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






15. Process that results in cell division






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






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






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






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






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






22. 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






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






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






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






26. Release of water from plants through stomata






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






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






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






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






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






32. Microtubule within a cell's nucleus; joined to one of the poles during cell division






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






34. Organelle containing genetic material






35. Useful for tearing and scratching






36. 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






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






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






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






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






41. The basic structural and functional unit of all organisms






42. Holds tissues together






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






44. Organelle in which proteins are synthesized






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






46. Process that results in cell division to produce gametes






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






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






49. Attaches to bones and is responsible for voluntary movements






50. Brain and spinal cord
