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. Organelle containing enzymes used in cell digestion






2. Brain and spinal cord






3. 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






4. Plant with specialized tissue for conducting water and nutrients






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






6. Process that results in cell division to produce gametes






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






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






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






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






11. Obsolete taxonomic group containing bacteria and cyanobacteria






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






13. 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.






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






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






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






17. Attaches to bones and is responsible for voluntary movements






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






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






20. Process that results in cell division






21. Contracts or shortens making body parts move






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






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






24. Any cell in a multicellular organism except the gametes






25. 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.






26. Sweat glands and sebaceous glands






27. 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






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






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






30. Division of the cytoplasm during cell division






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






32. Holds tissues together






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






34. Stores and releases bile






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






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






37. 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






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






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






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






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






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






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






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






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






46. Produce testosterone and sperm






47. Connective - muscle - nervous - epithelial






48. Produces and stores nutrients through photosynthesis






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






50. Produce progesterone and estrogens - in addition to eggs
