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. Discovered mitosis






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






3. Attaches to bones and is responsible for voluntary movements






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






5. 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






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






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






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






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






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






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






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






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






14. 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.






15. Largest organ in terms of surface area






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






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






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






19. Release of water from plants through stomata






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






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






22. Plants with no phloem - xylem - roots - stems - or leaves; not as large or intricate as vascular plants






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






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






25. 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.






26. Obsolete taxonomic group containing bacteria and cyanobacteria






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






28. Produces digestive enzymes and the hormones insulin and glucagons






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






30. Organelle containing genetic material






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






32. Cells that form the outer surface of plants






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






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






35. Plant with specialized tissue for conducting water and nutrients






36. 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.






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






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






39. Stores and releases bile






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






41. xylem and phloem; transport fluid and nutrients internally






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






43. Process that results in cell division to produce gametes






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






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






47. Sweat glands and sebaceous glands






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






49. Discovered meiosis






50. Connective - muscle - nervous - epithelial
