Across
  1. 3. -square shaped cell, contains cell wall and chloroplast.
  2. 4. -sequence of growth and division
  3. 7. -organelle in both plant and animals cells. Separates the inside of the cell from te outside.
  4. 8. -Division of the cytoplasm, form two separate daughter cells
  5. 10. -Rod shaped organelles converts energy in food molecules to energy the cell. The powerhouse.
  6. 11. -Cells become specialized in structure and function.
  7. 12. -thick,jelly like fluid, holds the organelles.
  8. 14. -Cell grows,performs its normal functions and prepares for division
  9. 16. -Contains a nucleus and membrane bound organelle.
  10. 19. -A rigid supporting layer,surrounding the cells of plants
  11. 20. -round shaped cell that contains a cell membrane,nucleus.
  12. 21. -Cell division,nucleus divide,nuclei containing the same number of chromosomes.
  13. 22. -Makes proteins
Down
  1. 1. -Whiplike tails,one celled organisms to aid movement.
  2. 2. -theory that mitochondria and chloroplasts originated as prokaryotic cells
  3. 5. -Hairlike projections, extend from the plasma membrane used for locomotion.
  4. 6. -tiny cell structure that carries out a specific function
  5. 9. -Unicellular organism, lacks a nucleus and membrane bound organelles.
  6. 13. -unspecialized cells, abilitiy to become a wide variety of specialized cells.
  7. 15. -A large oval organelle,contains cell's genetic material in form of DNA. Controls many cell activities.
  8. 17. -An organelle in the cells of plants. Changes into an energy form that cells can use to make food.
  9. 18. -A sac like organell that stores water,food
