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. Contracts or shortens making body parts move






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






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






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






5. Organelle containing enzymes used in cell digestion






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






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






8. Useful for tearing and scratching






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






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






11. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






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






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






17. Organelle in which proteins are synthesized






18. Release of water from plants through stomata






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






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






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






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






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






24. Organelle in which calcium levels are regulated






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






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






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






28. Produces and stores nutrients through photosynthesis






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






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






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






32. 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






33. Cells that form the outer surface of plants






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






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






36. Produce testosterone and sperm






37. Sweat glands and sebaceous glands






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






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






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






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






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






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






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






45. 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






46. Produces digestive enzymes and the hormones insulin and glucagons






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






48. Organelle containing genetic material






49. 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






50. Stores and releases bile
