Across
  1. 2. - The "powerhouse of the cell" where cellular respiration takes place to release energy.
  2. 4. - A type of reproduction involving only one parent, producing offspring that are exact genetic copies.
  3. 5. - Green structure in plant cells where photosynthesis happens.
  4. 8. - A tough, rigid outer layer outside the cell membrane that gives plant cells extra support and shape.
  5. 9. - The scientist who first looked at a slice of cork under a microscope in 1665 and gave cells their name.
  6. 11. - Fats, oils, and waxes used for long-term energy storage and cell membranes.
  7. 12. - The green pigment inside chloroplasts that absorbs sunlight for photosynthesis.
  8. 13. - The jelly-like fluid / space inside the cell.
  9. 15. - Any change in an organism's environment (such as light, temperature, or sound) that causes a reaction.
  10. 18. - The process where cells break down food molecules to release usable energy.
  11. 19. - Organisms that must get energy by eating other living things.
  12. 20. - Organisms that make their own organic matter.
  13. 21. - The single new cell formed during sexual reproduction.
  14. 24. - Storage bubbles inside cells that hold water, food, or waste.
  15. 26. – Nucleic acids that carry the instructions for building and running a living thing.
  16. 27. - A reproductive cell.
  17. 28. - A long, whip-like tail that helps certain cells swim and move.
  18. 29. - Complex molecules like DNA that store genetic instructions
  19. 30. - A more complex cell that has a nucleus and more organelles.
Down
  1. 1. - Tiny cellular factories that build proteins.
  2. 3. - Sugars and starches that provide quick energy.
  3. 6. - The process plants use to turn sunlight, water, and carbon dioxide into food (glucose) and oxygen.
  4. 7. - The process where a spermatozoo and an ovum join together.
  5. 10. - A group of similar cells working together to perform a specific job.
  6. 14. - Large molecules that build body structures and help in cellular activities.
  7. 16. - The flexible outer barrier that surrounds a cell and controls what enters and leaves.
  8. 17. - Small structures in animal cells that help organize cell division.
  9. 22. – example of autotrophic organisms.
  10. 23. - example of heterotrophic organisms.
  11. 25. - A protective outer layer found on some bacteria that helps them avoid danger.
