Cellular structure

Cellular structure refers to the organization and components of cells, which are the basic building blocks of all living organisms. Each cell is enclosed by a membrane that protects it and regulates what enters and exits. Within the cell, various structures called organelles carry out specific functions, such as producing energy (mitochondria), synthesizing proteins (ribosomes), and storing genetic information (nucleus). The arrangement and complexity of these components enable cells to perform vital tasks, contributing to the overall function and health of an organism. Understanding cellular structure is fundamental to biology and medicine.
