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 digesting and absorbing the extracted vital nutrients from food






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






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






4. Useful for tearing and scratching






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






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






7. 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






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






9. Release of water from plants through stomata






10. Discovered mitosis






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






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






13. Plant with specialized tissue for conducting water and nutrients






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






15. Organelle in which calcium levels are regulated






16. Organelle containing genetic material






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






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






19. 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






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






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






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






23. Organelle in which proteins are synthesized






24. Produces digestive enzymes and the hormones insulin and glucagons






25. Holds tissues together






26. Stores solid waste products






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






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






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






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






31. 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.






32. 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






33. Division of the cytoplasm during cell division






34. 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






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






36. Process that results in cell division to produce gametes






37. 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.






38. Largest organ in terms of surface area






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






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






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






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






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






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






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






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






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






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






49. 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






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