  4. 10. Is a type of cell that contains a nucleus and other membrane-bound organelles.
  5. 12. Is the basic unit of life, the smallest structure capable of performing all the functions necessary for an organism's survival.
  6. 13. They are made up of RNA and protein molecules and can be found either floating in the cytoplasm or attached to the endoplasmic reticulum.
  7. 17. Is a type of cell that lacks a nucleus and other membrane-bound organelles.
  8. 18. Are organelles that produce energy for the cell through cellular respiration

  1. 1. Is an organelle that contains enzymes that break down and recycle cellular waste and foreign material.
  2. 2. Is a thin, flexible layer that surrounds the cell and separates its contents from the outside environment.
  3. 3. Is the process of cell division that results in the formation of four genetically diverse daughter cells, which is important in sexual reproduction.
  4. 6. Is a network of protein fibers that provides structural support for the cell and helps with cell movement.
  5. 7. Is a rigid structure that surrounds the cell membrane in some cells, providing additional support and protection.
  6. 9. Is the process of cell division that results in the formation of two genetically identical daughter cells.
  7. 11. Is an organelle that plays a key role in the synthesis and transport of proteins and lipids.
  8. 12. Is a gel-like substance that fills the cell and contains the cell's organelles.
  9. 14. Are a type of cell that has the ability to differentiate into many different types of cells in the body.
  10. 15. Are specialized structures within a cell that perform specific functions.
  11. 16. Is an organelle that modifies, sorts, and packages proteins and lipids for transport.
