Biology!
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.
- 21. Body, small bags with tubes connecting them. packages and secretes proteins for use in and out of the cell.
- 22. brings material inside the cell.
- 23. the positively charged center of the atom.
- 27. the process in which green plants convert sunlight energy/water/and carbon dioxide into glucose and oxygen.
- 28. produces ribosomes.
- 32. ER, assembles proteins to transport material.
- 33. attraction between particles of the same substance.
- 34. the energy currency of all cells.
- 36. Diffusion, movement of large molecules across the membrane using special proteins.
- 38. the number of molecules in a given volume.
- 39. makes protein.
- 40. maintains cell shape/moves cell parts/helps cells move.
Down
- 1. takes material outside the cell.
- 2. supplies energy or ATP for the cell respiration using glucose and oxygen.
- 3. store tank for food water wastes or enzymes.
- 5. negatively charged particles in atoms found in an area called the electron cloud.
- 6. attraction between two different substances.
- 8. Number, the number of protons.
- 10. diffusion of water.
- 11. Mass, the mass of an atom/the number of protons and neutrons.
- 12. particles in the nucleus of an atom that have no charge.
- 13. gradual difference of concentration as particles move across a membrane.
- 15. provides the energy a cell needs to move.
- 16. Wall, protects and supports the cell.
- 18. any material that is made up of one type of atom.
- 20. pads/supports organelles inside the cell.
- 24. Membrane, protects the cell and performs active/passive transport. moves materials in/out of the cell.
- 25. ability to maintain a steady state despite changing conditions.
- 26. the breakdown of glucose by enzymes releasing energy and pyruvic acid.
- 29. Diffusion, movement of molecules across the membrane from high to low concentration.
- 30. organize cell division.
- 31. substance that is being dissolved.
- 35. positively charged particles in the nucleus of an atom.
- 37. Krebs Cycle, takes place in the mitochondria consuming oxygen and producing carbon dioxide and water as waste products.
