Answer:
1)The cell is known as the structural and functional unit of life because all living beings are formed of cells. Cells are very important for performing various life processes which are required for sustaining life on earth. Moreover, cells give form and structure, process nutrients and make it into usable energy.

Unicellular organisms include bacteria, protists, and yeast.
Answer:
answer of 1] the cell is our most essential body forming unit. Each organ in our body is all formed of cells. Cells divide and multiply in order to make new organs as well as gametes.
Cell is termed as a functional unit of life because of the following reasons-
The cell is known as the structural and functional unit of life because all living beings are formed of cells.

Moreover, cells give form and structure, process nutrients and make it into usable energy.
Multicellular organisms consist of specialized cells which perform specific functions.
Always keep in mind that, Cell is termed as a structural and functional unit of life because living organism/ beings consist of cells and all the physiological, biochemical, genetic and metabolic functions are performed inside of the cell. It is believed as the smallest functional unit that can exist independently
2]Cells function differently in unicellular and multicellular organisms. A unicellular organism depends upon just one cell for all of its functions while a multicellular organism has cells specialized to perform different functions that collectively support the organism.
