What are the advantages to a unicellular organism?

These are unicellular advantages:

 1. Not seen in the naked eye Unicellular organisms are not seen to the naked eye. Because of this, unicellular organisms are not easily identified by a lot of predators except of their own kind.

 2. Asexual organism Unicellular organisms don’t necessarily need a partner to be able to produce. Thus, saving a lot of energy in finding a mate is achieved. Also, unicellular organisms tend to multiply at high rates compared to other organisms.

 3. Less complicated
 Unicellular organisms are not that complicated in terms of parts. They are not made to have a lot of systems and are very much suited to flourish in many places.
