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






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






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






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






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






6. Produce progesterone and estrogens - in addition to eggs






7. Process that results in cell division






8. xylem and phloem; transport fluid and nutrients internally






9. 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






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






11. Stores solid waste products






12. Sweat glands and sebaceous glands






13. Largest organ in terms of surface area






14. Obsolete taxonomic group containing bacteria and cyanobacteria






15. Epidermis - vascular - ground






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






17. 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






18. Brain and spinal cord






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






20. Discovered meiosis






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






22. Protects the body and holds in heat






23. Contracts or shortens making body parts move






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






25. 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






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






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






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






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






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






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






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






33. 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.






34. Connective - muscle - nervous - epithelial






35. Division of the cytoplasm during cell division






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






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






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






39. 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.






40. Responsible for releasing several tropic hormones - which regulate the activity of other endocrine glands






41. 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






42. Holds tissues together






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






44. Plant with specialized tissue for conducting water and nutrients






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






46. Attaches to bones and is responsible for voluntary movements






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






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






49. Produces digestive enzymes and the hormones insulin and glucagons






50. Release of water from plants through stomata
