Across
- 1. An organelle that produces energy in the form of ATP for eukaryotic cells
- 7. Organelle that breaks down old cell parts and invading bacteria
- 9. An organism that must eat other organisms for energy
- 10. This type of transport requires an input of energy because movement is against the concentration gradient
- 12. An organism that has a nucleus and membrane bound organelles
- 15. Large geographic region with specific climate and organisms
- 18. A macromolecule made of amino acids
- 20. The process by which polymers are broken down into smaller monomers using water
- 22. An organelle that makes proteins through the process of translation
- 23. Organelle plants have that use sunlight and carbon dioxide to make glucose
- 25. Variable that the experimenter is testing the effect of
Down
- 2. Type of macromolecule that is the body's main source of energy
- 3. This type of solution has a lower solute concentration than the cell and causes cells to swell
- 4. Community of organisms interacting with nonliving factors
- 5. Water is this because its atoms share electrons unequally, causing partial charges
- 6. A semi-permeable barrier that is present around all cells
- 8. Protein that speeds up chemical reactions
- 11. The type of bond that is between water molecules and gives water unique properties
- 13. Nonliving factor in an ecosystem
- 14. Stable internal conditions within an organism
- 16. The monomer of nucleic acids
- 17. This type of cell is small and simple with no nucleus or membrane bound organelles
- 19. The nutrient cycle characterized by bacteria converting the nutrient into useable forms
- 21. The property of water being attracted to other water molecules
- 24. The type of population growth where the population levels off at carrying capacity
- 26. This type of homeostatic feedback mechanism reduces the intensity of a response to restore stability
