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. Largest organ in terms of surface area






2. Process that results in cell division






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






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






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






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






7. Produce testosterone and sperm






8. Stores solid waste products






9. Stores and releases bile






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






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






12. 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






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






14. 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






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






16. Organelle containing enzymes used in cell digestion






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






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






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






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






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






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






23. Attaches to bones and is responsible for voluntary movements






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






25. Plant with specialized tissue for conducting water and nutrients






26. Contracts or shortens making body parts move






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






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






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






30. Organelle containing genetic material






31. Release of water from plants through stomata






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






33. Epidermis - vascular - ground






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






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






36. Produces and stores nutrients through photosynthesis






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






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






39. 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.






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






41. xylem and phloem; transport fluid and nutrients internally






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






43. 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






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






45. Holds tissues together






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






47. Strands of plant tissue containing xylem and phloem - sometimes surrounded by a fiber covering






48. Organelle in which calcium levels are regulated






49. Any cell in a multicellular organism except the gametes






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