What is the smallest unit of cell?

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

Is the cell The smallest unit of matter?

Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms.

  2. Labour cost.
  3. Cost of equipment or Tools and plants( 1.5%)
  4. Water charges (1.5%)
  5. Overhead expenses (2 to 5%)
  6. Contractor profit (10%)

How do you calculate the cost of one unit?
