Answer 1

Hi friend,...thanks for the question...

Indeed, a cell is a building unit of an organism.

The cells are called as structural and functional units of a living body. Cells are structural unit as they form the structure of the organism. 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. Some of the basic ‘life processes’ or ‘functions’ takes place in every cell to keep the organisms alive such as digestion, respiration, excretion, etc., whether it is a single-celled organism or multicellular organism. So, the cells are also called the functional unit of life owing to these processes. In order to carry out all these things, cells need energy.The main energy source for most cells to function is ATP, which stands for adenosine triphosphate. ATP is obtained by breaking down glucose in the presence of oxygen. Just like a building is made of bricks an organism's body is made up of cells...

Answer 2

it is because cells  make up the smallest level of a living organism such as yourself and other living  things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the building unit of an organism.
