What are the main parts of a cell and their functions?

Cells are the basic building blocks of life. They have various parts, each with a specific function. The main parts of a cell include the cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum, and Golgi apparatus. The cell membrane regulates what enters and leaves the cell. The nucleus contains genetic material and controls cell activities. The cytoplasm is where organelles are suspended. Mitochondria produce energy. The endoplasmic reticulum synthesizes proteins and lipids. The Golgi apparatus processes and packages proteins. Understanding the functions of these parts is essential for understanding the complexities of living organisms.
