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






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






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






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






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






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






7. Plant with specialized tissue for conducting water and nutrients






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






9. Sweat glands and sebaceous glands






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






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






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






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






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






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






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






17. Stores solid waste products






18. Produces and stores nutrients through photosynthesis






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






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






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






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






23. 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.






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






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






26. Discovered mitosis






27. Largest organ in terms of surface area






28. In the life cycle of a plant or alga undergoing alternation of generations - a meiotically produced haploid cell that divides mitotically - generating a multicellular individual - the gametophyte - without fusing with another cell.






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






30. Division of the cytoplasm during cell division






31. Any cell in a multicellular organism except the gametes






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






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






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






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






36. Holds tissues together






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






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






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






40. 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






41. Brain and spinal cord






42. Discovered meiosis






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






44. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






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






46. 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






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






48. Obsolete taxonomic group containing bacteria and cyanobacteria






49. The basic structural and functional unit of all organisms






50. Process that results in cell division
