Across
  1. 2. Type of endoplasmic reticulum where ribosomes are not attached, here cellular substances are processed.
  2. 4. A botanist who in 1838 said that all plants are made of cells.
  3. 5. Said the cell is the basic unit of structure in animals.
  4. 8. Observed that all cell divide to form new cells.
  5. 10. Controls the movement of material in and out of the nucleus.
  6. 12. Type of endoplasmic reticulum where ribosomes are attached and where proteins are made.
  7. 14. Type of cell that is block shaped, has many tubes to soak up water, contains NO chloroplasts.
  8. 15. Breaks down large food molecules, waste and worn out parts of the cell.
  9. 16. Type of cell that carries oxygen through the body, flexible and small to fit through narrow passageways. NO NUCLEUS
  10. 17. Peanut shaped organelle that breaks down food to release energy.
  11. 18. Type of cell that is long and fibrous so it can contract and extend for movement, contains a lot of mitochondria.
  12. 23. A fluid-filled sac that stores water, waste, food and other cellular materials.
  13. 24. Regulates the interaction between the cell and its environment.
  14. 26. Site where ribosomes are made.
  15. 29. Tough rigid outer covering surrounding a cell and gives its structure and support.
Down
  1. 1. Encases, cushions and protects the internal organelles (Think JELL-O)
  2. 3. Contains chlorophyll, and is the site where photosynthesis takes place.
  3. 6. A molecule that can use light energy from sunlight to turn water and carbon dioxide gas into sugar and oxygen.
  4. 7. Type of cell that can change shape to fit between tissues, it finds and fights infections.
  5. 9. First person to observe living cells from a drop of pond water.
  6. 11. Its function is to process and move materials around the inside of the cell.
  7. 13. Flat, stacked membranes that sort and package proteins and other cellular substances.
  8. 19. Makes up the internal framework of the cell, gives cell its shape.
  9. 20. A membrane bound structure that delivers cellular substances to other areas inside the cell and carries substances to the cell membrane to be released from the cell.
  10. 21. Looked at cork and was the first person to see and observe cells.
  11. 22. Type of cell that is long and branched to send messages quickly to the brain.
  12. 25. The site where proteins are made.
  13. 27. Control all of the cell's activities.
  14. 28. Type of cell that is brick shaped and contains many chloroplasts to change light energy into food.
