I think the question you mean to ask is "do plants have an immune
system _like mammals_" rather than "like animals".  Reptiles don't
even have the kind of immune system mammals do.  On my (admittedly
limited) understanding, the mammalian immune system is pretty odd and
unusual, and its evolutionary origin isn't well understood.  (Repeat,
limited understanding.)
