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. Attaches to bones and is responsible for voluntary movements






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






3. 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






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






5. Discovered mitosis






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






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






8. Organelle containing genetic material






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






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






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






12. Plant with specialized tissue for conducting water and nutrients






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






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






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






16. Organelle containing enzymes used in cell digestion






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






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






19. Useful for tearing and scratching






20. Connective - muscle - nervous - epithelial






21. xylem and phloem; transport fluid and nutrients internally






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






23. Division of the cytoplasm during cell division






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






25. Epidermis - vascular - ground






26. Organelle in which lipids and steroids are produced - carbohydrates and steroids are metabolized - and calcium concentration - drug detoxification - and attachment of cell membrane receptors are regulated.






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






28. Process that results in cell division to produce gametes






29. Process that results in cell division






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






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






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






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






34. 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






35. Produce progesterone and estrogens - in addition to eggs






36. Holds tissues together






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






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






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






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






41. The basic structural and functional unit of all organisms






42. Organelle in which calcium levels are regulated






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






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






45. Stores solid waste products






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






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






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






49. Release of water from plants through stomata






50. 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
