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. The basic structural and functional unit of all organisms






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






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






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






7. Sweat glands and sebaceous glands






8. Contracts or shortens making body parts move






9. xylem and phloem; transport fluid and nutrients internally






10. Epidermis - vascular - ground






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






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






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






14. 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






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






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






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






18. Process that results in cell division






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






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






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






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






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






24. Produce testosterone and sperm






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






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






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






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






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






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






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






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






33. Useful for tearing and scratching






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






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






36. Brain and spinal cord






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






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






39. Cells that form the outer surface of plants






40. Stores and releases bile






41. 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.






42. Largest organ in terms of surface area






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






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






45. Organelle containing genetic material






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






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






48. 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






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






50. Process that results in cell division to produce gametes
