Why is cell division important for both single-celled and multicellular organisms?

Because it is a mode for reproduction and growth.

Explanation:

Cell division is important for both single-celled as well as multi-cellular organisms.

In single-celled organisms, the cell division is the process which helps them to reproduce and form new organisms.

In multi-cellular organism, the cell division becomes more important because both, the division and growth in cells of multi-cellular organism occurs by means of cell division. When cells divide, the number of cells increases and it is seen as a overall growth in the organism. Damaged tissue repair is also accomplished by the cell division itself.

answer; ///i believe that the correct answer is (a) specialized cells)

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
