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 releasing several tropic hormones - which regulate the activity of other endocrine glands






2. Produces and stores nutrients through photosynthesis






3. Plant with specialized tissue for conducting water and nutrients






4. 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






5. 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






6. Stores solid waste products






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






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






9. 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






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






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






12. Discovered mitosis






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






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






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






16. Third phase of mitosis and of meiosis I and II - in which the sister chromatids separate and move toward the poles of the spindle






17. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






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






19. 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






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






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






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






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






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






25. Process that results in cell division to produce gametes






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






27. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






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






33. Produce testosterone and sperm






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






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






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






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






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






39. Any cell in a multicellular organism except the gametes






40. 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






41. Protects the body and holds in heat






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






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






44. Connective - muscle - nervous - epithelial






45. Holds tissues together






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






47. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






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






49. 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.






50. Release of water from plants through stomata
