Transcript of "Biology 7 2"

  1. 1. Eukaryotic Cell Structure 7.2<br />
  2. 2. Organelle <br />Specialized structure that performs important cellular functions within a eukaryotic cell.<br />
  3. 3. Cytoplasm<br />Material inside the cell membrane not including the nucleus.<br />
  4. 4. Nuclear Envelope <br />Layer of two membranes that surrounds the nucleus of the cell. <br />
  5. 5. Chromatin<br />Granular material visible within the nucleus; consists of DNA tightly coiled around proteins.<br />
  6. 6. Chromosome <br />Threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next.<br />
  7. 7. Nucleolus <br />Small, dense region within most nuclei in which the assembly of proteins begins. <br />
  8. 8. Ribosome<br />Small particle in the cell on which proteins are assembled; made of RNA and protein. <br />
  9. 9. Endoplasmic Reticulum <br />Internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified.<br />
  10. 10. Golgi Apparatus <br />Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum.<br />
  11. 11. Lysosome <br />Cell organelle filled with enzymes needed to break down certain materials in the cell.<br />
  12. 12. Vacuole <br />Cell organelle that stores materials such as water, salts, proteins, and carbohydrates.<br />
  13. 13. Mitochondrion <br />Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.<br />
  14. 14. Chloroplast <br />Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy.<br />
  15. 15. Cytoskeleton<br />Network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement.<br />
  16. 16. Centriole <br />One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope. <br />
  17. 17. Key Concepts<br />What are the functions of the major cell structures?<br />The nucleus contains nearly all the cell’s DNA and with it the coded instructions for making proteins and other important molecules. <br />
