  1. 5. Cells that recognize one another will group together (Cancer cells do not recognize each other)
  2. 6. complementary copies of distinct DNA, the genetic code
  3. 7. Controls the two major functions of the cell: Chemical reactions—synthesizing activities
  4. 9. transporter of specific amino acids (building blocks of proteins)
  5. 11. Membrane-bound organelles responsible for the breakdown of foreign substances that are engulfed by the cell by the process of phagocytosis or pinocytosis
  6. 14. The building blocks of tissues in the body are attached to each other and to noncellular surfaces by
  7. 15. cells attach to each other by fusion of their cell membranes
  8. 17. Cells must have the ability to form substances that produce products to aid in the body’s function
  9. 20. Fluids, chemical elements, and compounds must have the ability to move both in and out of cells
  10. 23. allowing some substances to pass through it and others to be excluded
  11. 24. found floating freely in the cytoplasm (polyribosomes) or attached to the ER
  12. 25. Transitory, nonliving metabolic byproducts found in the cytoplasm of the cell
  13. 27. Referred to as plasma membrane or plasmalemma; usually too thin to be seen with a light microscope
  14. 28. Extensive membranous system found throughout the cytoplasm of the cell; composed of lipoprotein membranes existing in the form of connecting tubules and broad, flattened sacs
  15. 29. Fluid located inside the cells of the body
  16. 30. Permitting entrance and exit of selected substrates
Down
  1. 1. the attachment of a cell to a noncellular surface
  2. 2. Translucent, aqueous, homogeneous gel enclosed in the cell by the cell membrane
  3. 3. Chemicals appear early in the development of the embryo
  4. 4. contain a channel that runs between cells for communication of cell electrical impulses and passage of molecules
  5. 8. This structure provides the chief source of energy for the cell (“powerhouse of the cell” by oxidation of nutrients) through enzymatic breakdown of fats, amino acids, and carbohydrates
  6. 10. the delicate balance maintained between the two fluid compositions
  7. 12. Smallest structures and functionally self-contained units in the body
  8. 13. Change in the environment stimulates the cell to bring about a response to adapt to a change
  9. 16. Cells must have the ability to preserve the species by giving rise to offspring
  10. 18. Fluid mass that circulates outside and between cells
  11. 19. The structure consists of stacks of closely spaced membranous sacs, in which newly formed proteins are concentrated and prepared for export out of the cell
  12. 21. cell-to-cell attachments
  13. 22. rough-surfaced endoplasmic reticulum (RER)
  14. 26. smooth-surfaced endoplasmic reticulum (SER)
