The Cell
Across
- 3. Cell A complex cell with a nucleus and membrane-bound organelles.
- 7. The control center of the cell that contains DNA.
- 9. Wall A rigid layer outside the cell membrane in plant cells that provides support and protection.
- 11. The "powerhouse" of the cell that produces energy.
- 13. Cell A simple cell without a nucleus, like bacteria.
- 14. Reticulum (ER) A network of membranes involved in protein and lipid synthesis.
- 17. Division The process by which a cell splits into two new cells.
- 18. Small sacs filled with enzymes that break down waste materials and cellular debris.
- 19. The movement of water across a membrane.
Down
- 1. The jelly-like substance inside the cell where most cellular activities occur.
- 2. Specialized structures within a cell that perform specific functions.
- 4. Tiny structures that make proteins.
- 5. Organelles found in plant cells that capture light energy and convert it to food through photosynthesis.
- 6. Transport The movement of substances across the cell membrane using energy.
- 8. A storage sac that can hold water, nutrients, or waste products.
- 9. Membrane The outer boundary of the cell that controls what enters and exits the cell.
- 10. The movement of molecules from an area of high concentration to low concentration.
- 12. (Deoxyribonucleic Acid) The genetic material that carries information about an organism.
- 15. A thread-like structure made of DNA that carries genetic information.
- 16. Apparatus The "packaging center" that modifies and sorts proteins and lipids.
