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






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






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






4. 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






5. 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






6. Epidermis - vascular - ground






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






8. Discovered meiosis






9. Attaches to bones and is responsible for voluntary movements






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






11. Connections between plant cells that allow fluids and nutrients to be shared






12. 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






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






14. Organelle in which proteins are synthesized






15. Plant with specialized tissue for conducting water and nutrients






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






17. Brain and spinal cord






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






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






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






21. Produce progesterone and estrogens - in addition to eggs






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






23. Release of water from plants through stomata






24. Stores and releases bile






25. Organelle containing enzymes used in cell digestion






26. Discovered mitosis






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






28. Any cell in a multicellular organism except the gametes






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






30. Organelle in which calcium levels are regulated






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






32. Contracts or shortens making body parts move






33. Division of the cytoplasm during cell division






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






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






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






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






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






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






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






41. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






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






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






44. Holds tissues together






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






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






47. Useful for tearing and scratching






48. 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






49. Largest organ in terms of surface area






50. xylem and phloem; transport fluid and nutrients internally
