why is the cell called the structural and functional unit of life
Answers
. Thus , cell 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 organelles 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., lysosomes ) , utilisation of oxygen in oxidation of food and energy production ( e.g., mitochondria ) , movement ( microtubules containing spindles , cilia , flagella ) , etc . A cell is able to live 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 .
Cell is called structural and fundamentalunit of life because body of all the organisms is made up of cells. It isfunctional unit of life because all the functions of body (physiological, biochemical. genetic and other metabolic functions) are carried out by cells.
Cells as Building Blocks. A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
The cells are called as structural and functional units of a living body. ... Cells combine to form tissues, which further combine to form organs, organs combine to form organic systems, which further combine to form organism. So, cell is the basic structural unit for all unicellular and multicellular organisms.
