The Animal cell

3. Provide mechanical support for the cell and help maintain its integrity.
5. Openings in the nuclear envelope that allow the passage of materials between the nucleus and cytoplasm.
8. The control center of the cell containing DNA and responsible for regulating gene expression and cell activities.
10. Proteins Embedded proteins that assist in cell communication, signaling, and transport.
16. The powerhouse of the cell that produces energy (ATP) through cellular respiration.
17. A network of membranes involved in protein and lipid synthesis.
18. A small membrane-bound sac used for transporting materials within the cell.
19. Contains digestive enzymes that break down waste, damaged organelles, and invading pathogens.
20. The form of DNA when it is loosely coiled in the nucleus; it condenses into chromosomes during cell division.

1. A double membrane that surrounds the nucleus and contains nuclear pores for transport.
2. Breaks down fatty acids and detoxifies harmful substances.
4. Organelles involved in cell division, helping organize the spindle fibers.
6. A small structure that synthesizes proteins; can be free-floating or attached to the endoplasmic reticulum.
7. A semi-permeable barrier that controls what enters and exits the cell.
9. Packages, modifies, and ships proteins and lipids for transport within or outside the cell.
11. Found inside the nucleus, it produces ribosomes.
12. A jelly-like substance where all cell organelles are suspended and where cellular processes occur.
13. of the cytoskeleton, important for maintaining cell shape and enabling transport and cell division.
14. A network of protein filaments that provides shape, support, and aids in movement within the cell.
15. Structures that connect animal cells to one another, allowing communication and adhesion (e.g., tight junctions, gap junctions, desmosomes).
