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






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






3. 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.






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






5. Produces and stores nutrients through photosynthesis






6. 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






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






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






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






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






11. Stores and releases bile






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






13. Epidermis - vascular - ground






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






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






16. 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






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






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






19. Cells that form the outer surface of plants






20. Discovered meiosis






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






22. Connective - muscle - nervous - epithelial






23. 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






24. Process that results in cell division to produce gametes






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






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






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






28. Produce progesterone and estrogens - in addition to eggs






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






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






31. Produce testosterone and sperm






32. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






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






34. Division of the cytoplasm during cell division






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






36. Attaches to bones and is responsible for voluntary movements






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






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






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






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






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






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






43. 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






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






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






46. Contracts or shortens making body parts move






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






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






49. Brain and spinal cord






50. The basic structural and functional unit of all organisms
