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






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






3. 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.






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






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






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






7. 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






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






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






10. Release of water from plants through stomata






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






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






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






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






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






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






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






18. Plant with specialized tissue for conducting water and nutrients






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






20. xylem and phloem; transport fluid and nutrients internally






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






22. Organelle in which proteins are synthesized






23. 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.






24. Responsible for transporting materials throughout the body: heart - blood (red - white - platelets) - blood vessels (arteries - vein - capillaries)






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






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






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






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






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






30. 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






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






32. Holds tissues together






33. Process that results in cell division to produce gametes






34. Epidermis - vascular - ground






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






36. Produce testosterone and sperm






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






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






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






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






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






42. Process that results in cell division






43. Sweat glands and sebaceous glands






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






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






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






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






48. Cells that form the outer surface of plants






49. Useful for tearing and scratching






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