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






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






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






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






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






6. Stores solid waste products






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






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






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






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






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






12. Holds tissues together






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






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






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






16. Organelle in which calcium levels are regulated






17. Produce testosterone and sperm






18. Obsolete taxonomic group containing bacteria and cyanobacteria






19. Organelle in which proteins are synthesized






20. 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.






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






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






23. Any cell in a multicellular organism except the gametes






24. Produce progesterone and estrogens - in addition to eggs






25. Sweat glands and sebaceous glands






26. 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.






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






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






29. 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






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






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






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






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






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






35. Process that results in cell division






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






38. The basic structural and functional unit of all organisms






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






40. 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






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






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






43. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






48. Discovered mitosis






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






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