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






2. Produce progesterone and estrogens - in addition to eggs






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






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






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






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






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






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






9. Organelle containing genetic material






10. Any cell in a multicellular organism except the gametes






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






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






13. Stores solid waste products






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






15. Discovered meiosis






16. Division of the cytoplasm during cell division






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






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






19. Sweat glands and sebaceous glands






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






21. Contracts or shortens making body parts move






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






23. 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






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






25. 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






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






27. Organelle in which calcium levels are regulated






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






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






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






31. Stores and releases bile






32. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






37. Process that results in cell division






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






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






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






42. Discovered mitosis






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






44. Attaches to bones and is responsible for voluntary movements






45. Epidermis - vascular - ground






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






47. Holds tissues together






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






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






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