Across
- 2. Gives plant cells support and protection.
- 4. Produces ATP, the usable energy of the cell.
- 5. Jelly-like substance where many chemical reactions occur.
- 10. Small, finger-like projections of the cell membrane that increase the surface area for absorption.
- 12. Contains the cell's DNA and controls many cell activities.
- 13. These cells contain a high concentration of mitochondria, which produce ATP to provide the energy needed for muscle contraction.
- 14. Cells in this organ have a large number of ribosomes because they produce and secrete large amounts of digestive enzymes (proteins).
- 15. A network of protein fibers that helps maintain cell shape.
Down
- 1. Plant-cell organelle where photosynthesis occurs.
- 3. Modifies, sorts, and packages proteins.
- 6. An organelle that exists in two forms: rough, which has ribosomes and helps make proteins, and smooth, which lacks ribosomes and helps make lipids and detoxify harmful substances.
- 7. Controls what enters and leaves the cell.
- 8. The organelle that makes ribosome components.
- 9. Makes proteins using instructions from mRNA.
- 11. Contains enzymes that break down waste and worn-out cell parts.
