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






2. Protects the body and holds in heat






3. 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






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






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






6. Cells that form the outer surface of plants






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






10. Useful for tearing and scratching






11. 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.






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






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






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






15. 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






16. xylem and phloem; transport fluid and nutrients internally






17. Organelle containing enzymes used in cell digestion






18. 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.






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






20. Brain and spinal cord






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






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






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






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






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






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






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






28. 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.






29. Process that results in cell division to produce gametes






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






31. Contracts or shortens making body parts move






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






33. 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






34. Largest organ in terms of surface area






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






36. Discovered mitosis






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






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






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






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






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






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






43. Connective - muscle - nervous - epithelial






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






45. Any cell in a multicellular organism except the gametes






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






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






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






49. The basic structural and functional unit of all organisms






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