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






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






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






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






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






6. Produce testosterone and sperm






7. Organelle containing genetic material






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






9. Organelle in which proteins are synthesized






10. Attaches to bones and is responsible for voluntary movements






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






12. Stores and releases bile






13. Discovered meiosis






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






15. 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






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






17. Protects the body and holds in heat






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






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






20. Holds tissues together






21. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






27. Division of the cytoplasm during cell division






28. Largest organ in terms of surface area






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






30. Useful for tearing and scratching






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






32. Stores solid waste products






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






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






35. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






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






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






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






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






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






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






42. 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






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






44. Process that results in cell division






45. Produces and stores nutrients through photosynthesis






46. Produces digestive enzymes and the hormones insulin and glucagons






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






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






49. Discovered mitosis






50. Group of similarly constructed cells that perform the same function within a multicellular organism
