Question

Indentify the single cell organism from the following Cockroach Chlamidomonos Snake Mosquito Bacteria

Answer 1

Clamydomonas is the odd one because it's single celled

Answer 2

Chlamydomonas is the single cell organism in the given list.    

  The single cell organism is composed of one cell only. Here Chlamydomonas is a single cell green alga. It has two anterior flagella with a single cup-shaped chloroplast. Each cell of Chlamydomonas is close to 10 micrometers.

  Similarly, bacteria are also single cell organism as they are part of prokaryotes. Hence both bacteria and Chlamydomonas must be correct answer here. But most probably Chlamydomonas is a perfect single-celled organism.
