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






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






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






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






5. Cells that form the outer surface of plants






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






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






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






9. Process that results in cell division






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






11. Organelle containing genetic material






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






13. Organelle containing enzymes used in cell digestion






14. Plant with specialized tissue for conducting water and nutrients






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






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






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






18. 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.






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






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






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






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






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






24. Organelle in which calcium levels are regulated






25. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






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






27. Release of water from plants through stomata






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






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






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






31. Any cell in a multicellular organism except the gametes






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






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






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






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






36. Holds tissues together






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






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






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






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






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






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






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






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






45. Division of the cytoplasm during cell division






46. Protects the body and holds in heat






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






48. Stores solid waste products






49. Sweat glands and sebaceous glands






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