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






2. 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.






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






4. Plant with specialized tissue for conducting water and nutrients






5. Largest organ in terms of surface area






6. Cells that form the outer surface of plants






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






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






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






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






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






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






13. Protects the body and holds in heat






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






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






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






17. Useful for tearing and scratching






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






19. Produce testosterone and sperm






20. Connective - muscle - nervous - epithelial






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






22. Organelle in which calcium levels are regulated






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






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






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






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






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






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






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






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






31. Organelle containing enzymes used in cell digestion






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






33. 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






34. Any cell in a multicellular organism except the gametes






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






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






37. 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.






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






39. Division of the cytoplasm during cell division






40. Stores and releases bile






41. Stores solid waste products






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






43. Obsolete taxonomic group containing bacteria and cyanobacteria






44. Sweat glands and sebaceous glands






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






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






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






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






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






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