Is the exhibition of memory an instinct?

[Pozessed]

Plants and microbes are considered to have some ability to use memory. I am curious if this ability to retain and recollect information should be considered instinctual, and to what degree as they have no brain or nervous system.

How are we defining instinct in this discussion?

[kisai]

Isn't instinctual behavior used to contrast with a learned (or conditioned) behavior? I'm not certain how useful it would be to differentiate a behavior that there is nothing else to differentiate it from.
