Function of Cell Parts

14. Nucleus
- Function: The control center of the cell. It contains the cell's DNA (genetic material) and controls cellular activities such as growth, metabolism, and reproduction.

15. Endoplasmic Reticulum (ER)
- Function: A network of membranous tubules and sacs involved in protein and lipid synthesis. There are two types:
- Rough ER: Covered with ribosomes; involved in protein synthesis.
- Smooth ER: Lacks ribosomes; involved in lipid synthesis and detoxification.

16. Cell Wall
- Function: Provides structural support, protection, and maintains the shape of the plant cell. It is made primarily of cellulose and is rigid.

17. Ribosome
- Function: Sites of protein synthesis. Ribosomes read mRNA and assemble amino acids into proteins.

18. Cytoplasm
- Function: The gel-like substance inside the cell membrane where most cellular activities occur. It contains organelles and supports their functions.

19. Nucleolus
- Function: A dense region within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomal subunits are assembled.

20. Golgi Body (Golgi Apparatus)
- Function: Modifies, sorts, packages, and distributes proteins and lipids produced by the cell. It also produces lysosomes and vesicles for secretion.

21. Cell Membrane (Plasma Membrane)
- Function: Regulates the movement of substances in and out of the cell. It is selectively permeable and maintains the internal environment of the cell.

22. Cytoskeleton
- Function: Provides structural support, maintains cell shape, and facilitates the movement of organelles and materials within the cell. It is composed of microtubules, microfilaments, and intermediate filaments.

23. Lysosome
- Function: Contains digestive enzymes that break down waste materials, cellular debris, and foreign particles. They also play a role in programmed cell death (apoptosis).

24. Mitochondrion
- Function: The powerhouse of the cell. It generates energy in the form of ATP (adenosine triphosphate) through cellular respiration.

25. Vacuole
- Function: A large, membrane-bound sac that stores water, nutrients, waste products, and other substances. In plant cells, it helps maintain turgor pressure and regulates the internal environment.

26. Chloroplast
- Function: The site of photosynthesis. Chloroplasts contain chlorophyll, which captures light energy to convert carbon dioxide and water into glucose and oxygen.
