Why is the cell called the structural and functional unit of life

Explanation

All living organisms aer made up of cells. Thus, cells is the structural unit of life. Each living cell has the capacity to perform certain basic functions that are characteristics of all living forms. Each cell acquired distinct structure and function due to the organization of its membrane and cytoplasmic organeles in specific way. Each kind of cell organelle performs a special function, such as making new materials in the cell (e.g., chloroplast, ribosomes), clearing up the waste materials from the cells (e.g., mitochondria), mivement (microtubules containing spindle, cilia, flagella), etc. A cell is able to live and perform all its functions because of these organelles. These organelles together constitute the basic unit of structure and function called the cell.
