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






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






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






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






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






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






7. Release of water from plants through stomata






8. 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






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






10. Organelle containing genetic material






11. 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






12. Organelle in which calcium levels are regulated






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






14. Largest organ in terms of surface area






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






16. 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.






17. xylem and phloem; transport fluid and nutrients internally






18. Process that results in cell division to produce gametes






19. Discovered mitosis






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






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






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






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






24. Holds tissues together






25. Organelle in which proteins are synthesized






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






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






28. Produces and stores nutrients through photosynthesis






29. Process that results in cell division






30. Division of the cytoplasm during cell division






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






32. Connective - muscle - nervous - epithelial






33. Discovered meiosis






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






35. Produce testosterone and sperm






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






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






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






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






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






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






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






43. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






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






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






46. Cells that form the outer surface of plants






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






48. Produce progesterone and estrogens - in addition to eggs






49. 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.






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