The Taxonomic Status of Fungi

According to five kingdom system of classification, 'Fungi' is now a
separate kingdom. Fungi have resemblance With plants in (1) having cell wall
(2)lack centriole (3) are non-motile.

Fungi resemble animals in having (a) are heterotrophs (b) lack
cellulose in their call Wall and contain chitin so it is thought that fungi and
animals arise from common ancestors. Fungi are different from animals in
having (i) cell wall (ii) are absorptive heterotrophs (iii) non-motile so fungi are neither plants nor animals. 

Fungi have (1) DNA different from all other
organisms (2) They show "Nuclear Mitosis" During nuclear mitosis nuclear
envelope does not break, instead the mitotic spindle forms within the nucleus
and the nuclear membrane constricts between the two clusters of daughter
chromosomes. In some fungi nuclear envelope dismantles late.
