Across
- 2. theory All living things are made of cells, the cell is the basic unit of life, and all cells come from pre-existing cells.
- 3. respiration Process that makes energy (ATP) from glucose and oxygen.
- 6. Network of membranes that transport materials (rough ER has ribosomes, smooth ER makes lipids).
- 9. Makes ribosomes inside the nucleus.
- 11. Builds proteins from instructions in mRNA.
- 13. Plant organelles that store pigments or food.
- 15. Controls what enters and leaves the cell.
- 19. Storage sac for water, nutrients, or waste.
- 20. Region that organizes microtubules.
- 22. Small transport sac in the cell.
- 24. Unwound DNA found in the nucleus.
- 25. Molecule that stores genetic instructions.
- 26. Site of photosynthesis in plant cells.
- 27. Diffusion of water across a membrane.
- 28. Specialized structure within a cell with a function.
- 30. Breaks down fatty acids and neutralizes toxins.
- 31. Provides structure, shape, and helps movement.
- 32. Process in plants that makes food using sunlight, water, and carbon dioxide.
- 33. Movement of molecules from high to low concentration.
