Homonym: cell (Prison)
A cell is the basic unit of life, serving as the building block for all living organisms. Cells can be classified into two main types: prokaryotic cells, which lack a nucleus and are generally smaller, and eukaryotic cells, which have a nucleus and are larger. Each cell contains various structures called organelles that perform specific functions, such as energy production and waste removal.
Cells reproduce through a process called cell division, which allows them to grow, repair, and maintain the organism. They also communicate with each other through chemical signals, enabling coordination and response to environmental changes. Understanding cells is essential for fields like biology and medicine.
