Across
  1. 3. proteins
  2. 5. envelope-layer of two membranes that surrounds the nucleus of a cell
  3. 7. jellylike fluid inside the cell in which the organelles are suspended
  4. 10. in animal cells containing centrioles from which the spindle fibers develop.
  5. 12. pores-holes in the nuclear envelope that allow materials to pass in and out of the nucleus
  6. 15. fold on the surface of a villus cell. These folds increase the surface area so that digested food is absorbed more quickly. Plural is microvilli.
  7. 17. oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals
  8. 18. complex-Organelle that packages and distributes proteins
  9. 19. nucleoplasm is a highly viscous liquid contained within the nucleus that surrounds the chromosomes and other subnuclear organelles.
Down
  1. 1. part of the cell containing DNA and RNA and responsible for growth and reproduction
  2. 2. membrane-A cell structure that controls which substances can enter or leave the cell.
  3. 4. vesicles-secrete substances outside the cell by exocytosis
  4. 6. organelle containing digestive enzymes
  5. 7. like motile projection from the surface of a cell
  6. 8. Endoplasmic Reticulum-An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down.
  7. 9. organelle that aids in cell division in animal cells only
  8. 11. Endoplasmic Reticulum-System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm
  9. 13. organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
  10. 14. fluid INSIDE of the NUCLEUS, very similar to the cytoplasm.
  11. 16. stored in the nucleus of an atom
