Across
- 4. captures sunlight and uses it to produce food through photosynthesis.
- 7. Respiration, the process that releases energy from food in the presence of oxygen.
- 9. ER, assembles lipids to transport material.
- 14. the smallest unit of an element that keeps the properties of that element.
- 17. provides instructions for the cell activities.
- 19. digests older parts food or other biomolecules.
