Cells are the fundamental units of life, forming the basis of all living organisms, and can be classified as prokaryotic or eukaryotic based on the presence of membrane-bound nuclei and organelles. The cell theory, formulated by Schleiden and Schwann, posits that all living organisms are composed of cells that arise from pre-existing cells. This chapter explores the structure and function of various cell organelles, emphasizing their roles in maintaining life's processes.
