Across
- 3. Part of the cell containing DNA and RNA and responsible for growth and reproduction
- 5. A selectively-permeable phospholipid bilayer forming the boundary of the cells
- 8. Modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
- 10. Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon, hydrogen, and oxygen.
- 11. process by which a cell takes material into the cell by infolding of the cell membrane
- 15. Process by which a cell releases large amounts of material
- 16. No nucleus
- 18. Has a nucleus
- 19. Organelle found in plant and algae cells where photosynthesis occurs
- 20. Organelle that stores materials such as water, salts, proteins, and carbohydrates
- 21. Proteins that speed up chemical reactions
Down
- 1. Process by which ATP is synthesized by using chemicals as an energy source
- 2. Extensive membranous network in eukaryotic cells, continuous with the outer nuclear membrane and composed of ribosome-studded (rough) and ribosome-free (smooth) regions.
- 4. Starches and sugars present in foods
- 6. Chains of amino acids
- 7. Conversion of light energy from the sun into chemical energy.
- 9. Adenosine triphosphate, main energy source that cells use for most of their work
- 12. Acids Macromolecules containing hydrogen, oxygen, nitrogen, carbon, and phosphorus
- 13. Organelle where proteins are assembled
- 14. Organelle containing digestive enzymes
- 17. Organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
- 19. Respiration Process by which cells break down simple food molecules to release the energy they contain.
