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






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






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






4. Process that results in cell division to produce gametes






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






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






7. 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.






8. 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.






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






10. Plant with specialized tissue for conducting water and nutrients






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






12. Release of water from plants through stomata






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






14. 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






15. Cells that form the outer surface of plants






16. Stores and releases bile






17. The basic structural and functional unit of all organisms






18. Produce progesterone and estrogens - in addition to eggs






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






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






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






22. Process that results in cell division






23. 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






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






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






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






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






28. Connective - muscle - nervous - epithelial






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






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






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






32. Sweat glands and sebaceous glands






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






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






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






36. 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






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






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






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






40. Holds tissues together






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






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






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






44. 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






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






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






47. Organelle in which proteins are synthesized






48. Attaches to bones and is responsible for voluntary movements






49. Stores solid waste products






50. Any cell in a multicellular organism except the gametes
