Which of the following organisms is larger in size, a bacterium with 2 micrometer or a chloroplast with 0.003 millimeter? State your reasons and show your computation.

Answer 1

A chloroplast with 0.003 millimeter

1mm=1000 micrometers

0.003 mm=?

0.003×1000=3 micrometer

The average diameter of bacteria is 0.2 to 2 micrometer.
