==Fungi resemblance==

''Phytophthora'' is sometimes referred to as a [[fungi|fungal]]-like organism but it is classified under a different kingdom altogether: [[Chromalveolata]] (formerly [[heterokont|Stramenopila]] and previously [[Chromista]]). This is a good example of [[convergent evolution]]: ''Phytophthora'' is morphologically very similar to true fungi yet its evolutionary history is quite distinct. In contrast to fungi, stramenopiles are more closely related to plants than animals. Whereas fungal cell walls are made primarily of [[chitin]], stramenopile cell walls are constructed mostly of [[cellulose]]. Ploidy levels are different between these two groups; Phytophthora have [[diploid]] (paired) chromosomes in the vegetative (growing, non-reproductive) stage of life, Fungi are almost always [[haploid]] in this state. Biochemical pathways also differ, notably the highly conserved [[Lysine]] synthesis path.
