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






2. Produce progesterone and estrogens - in addition to eggs






3. xylem and phloem; transport fluid and nutrients internally






4. Produce testosterone and sperm






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






6. Process that results in cell division to produce gametes






7. Division of the cytoplasm during cell division






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






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






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






11. Brain and spinal cord






12. Produces digestive enzymes and the hormones insulin and glucagons






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






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






15. 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.






16. Sweat glands and sebaceous glands






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






18. Contracts or shortens making body parts move






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






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






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






22. 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.






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






24. Organelle in which calcium levels are regulated






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






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






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






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






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






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






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






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






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






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






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






36. Epidermis - vascular - ground






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






38. Organelle in which proteins are synthesized






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






40. Process that results in cell division






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






42. Stores and releases bile






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






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






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






46. Organelle containing enzymes used in cell digestion






47. Cells that form the outer surface of plants






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






49. Release of water from plants through stomata






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