Cells

Cells are the fundamental structural and functional units of living organisms. All organisms, whether unicellular (such as bacteria and yeast) or multicellular (such as plants, animals, and humans), are composed of cells. Cell biology is the scientific discipline dedicated to studying cell structure, function, and behavior. Through advancements in microscopy, cell culture, and molecular biology techniques, scientists continuously deepen their understanding of cellular mechanisms, providing essential foundations for fields such as medicine, genetics, and biotechnology. Cells are the fundamental units of life, and comprehending their structure and function is vital for the advancement of biology and medicine.
