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






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






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






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






5. Protects the body and holds in heat






6. Connective - muscle - nervous - epithelial






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






8. Produces and stores nutrients through photosynthesis






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






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






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






12. Release of water from plants through stomata






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






14. 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.






15. Organelle in which proteins are synthesized






16. Produces digestive enzymes and the hormones insulin and glucagons






17. 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.






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






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






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






21. Brain and spinal cord






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






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






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






25. 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.






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






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






28. Organelle in which calcium levels are regulated






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






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






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






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






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






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






35. 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






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






37. Discovered meiosis






38. Process that results in cell division






39. Obsolete taxonomic group containing bacteria and cyanobacteria






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






41. Any cell in a multicellular organism except the gametes






42. Sweat glands and sebaceous glands






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






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






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






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






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






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






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






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