Identify the characteristic that is unique to fungi:
(1) Cell wall of glucans and chitin
(2) Lack of chloroplasts and heterotrophic nutrition
(3) Mannitol, trehalose and glycogen as storage products.
(4) Having haploid nuclei and production of spores
(1) The fungal cell wall is composed of glucans and chitins; while glucans are also found in plants and chitin in the exoskeleton of arthropods, fungi are the only organisms that combine these two structural molecules in their cell wall.
