  1. 2. A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level
  2. 5. Control center of the cell
  3. 8. Found inside the nucleus and produces ribosomes
  4. 10. A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
  5. 11. A unicellular organism that lacks a nucleus and membrane bound organelles
  6. 12. Pressure that a fluid exerts against a structure that contains it
  7. 14. idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
  8. 15. An organelle containing digestive enzymes
  9. 17. A system of membranes that modifies and packages proteins for export by the cell
  10. 18. A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
  11. 19. Process in which cells become specialized in structure and function
Down
  1. 1. Powerhouse of the cell, organelle that is the site of ATP (energy) production
  2. 3. The adaptation of an organism or organ to a special function or environment
  3. 4. A cell structure that controls which substances can enter or leave the cell. Also known as the Plasma Membrane
  4. 6. A cell that contains a nucleus and membrane bound organelles
  5. 7. Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
  6. 9. A phenomenon in walled cells in which the cytoplasm shrivels and the plasma membrane pulls away from the cell wall; occurs when the cell loses water to a hypertonic environment.
  7. 13. Cytoplasmic organelles at which proteins are synthesized.
  8. 14. An organelle found in plant and algae cells where photosynthesis occurs
  9. 16. A tiny cell structure that carries out a specific function within the cell
