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. Protects the body and holds in heat






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






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






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






5. Useful for tearing and scratching






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






7. Attaches to bones and is responsible for voluntary movements






8. Any cell in a multicellular organism except the gametes






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






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






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






12. 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.






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






14. Organelle in which calcium levels are regulated






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






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






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






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






19. Brain and spinal cord






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






21. Epidermis - vascular - ground






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






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






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






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






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






27. Organelle that 'packages' proteins to be secreted from the cell






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






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






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






31. Stores solid waste products






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






33. 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






34. Process that results in cell division






35. Organelle containing genetic material






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






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






38. Sweat glands and sebaceous glands






39. xylem and phloem; transport fluid and nutrients internally






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






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






42. Nutrient conducting plant tissue; formed like small tubules; living cells






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






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






45. Produce testosterone and sperm






46. Contracts or shortens making body parts move






47. Structure within a cell that is responsible for a specific function






48. Obsolete taxonomic group containing bacteria and cyanobacteria






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






50. Produces digestive enzymes and the hormones insulin and glucagons
