Fungi grow in moist and warm conditions. Refrigerator provides dry and cold conditions that prevent fungal growth. Therefore food stored in refrigerator doesn’t get rotten.

Fungi prefer warm and moist conditions to grow. All the fungi are multi-cellular eukaryotic organisms except yeast. Fungi are heterotrophic and are either parasitic or saprophytic. Parasitic fungi sometimes cause diseases. Fungi are immobile and this is the major difference between slime molds and that of fungi.

In obligative symbiosis, both the organisms get benefitted and this symbiosis is necessary for both of their survival. Symbiotic relationship between honey bee and flowers is necessary for their survival because honey bees needs nectar from flowers and in turn help flowers with pollination.

Lice in humans are example of exo-symbiosis. Fungi are heterotrophic and can be either saprophytic or parasitic. Some of the parasitic fungi can cause diseases in humans. Lichens are an example of obligative symbiosis. Cell wall of fungi is made of chitin and polysaccharides.

Fungus reproduces through asexual mode during favourable conditions and opts sexual mode of reproduction only during adverse situations. Budding, fragmentation and spore formation are different modes of asexual reproduction. Zoospores and zygospores are produced by phycospores for asexual and sexual odes of reproduction respectively.

The word “coeno” means common and “cytic” means cytoplasm. Therefore the word “coenocytic” means sharing of common cytoplasm. Aseptate fungi have multiple nuclei in a common cytoplasm.

During reproduction of fungus through fragmentation, Mycelium separates into pieces which in turn grow to form new mycelium. Fragmentation is one of the most common modes of asexual reproduction in Basidiomycetes.

Asexual spores in Ascomycetes are called Conidia and are produced exogenously by conidiocarps. Sexual spores in Ascomycetes are called Ascospores and are produced endogenously in asci present inside Ascocarps.

Non-motile spores in Phycomycetes are called as Aplanospores and motile spores are known as Zoospores. Fusion of similar or dissimilar gametes through sexual mode results in Zygospores.

Zygospores are formed either due to isogamous or anisogamous fertilization. Zoospores and aplanospores are motile and non-motile spores produced due to asexual mode respectively. Phycomycetes are aseptate fungi and are coenocytic. Phycomycetes are also called as algal fungi or conjugation fungi.

Rhizopus also called as bread mold belongs to Phycomycetes or conjugation fungi. Other well known examples of Phycomycetes or Conjugation fungi are Mucor and Albugo (Mustard fungi).

Phycomycetes are also called as Conjugation fungi. Because, phycomycetes can reproduce using dissimilar gametes i.e. anisogamous fertilization can take place and hence came the name conjugation fungi.

A phase in the life cycle of certain fungi in which sexual spores are formed, as the asci in the sexual stage of the ascomycetes it is referred to as the perfect stage.

The word “karyo” means nucleus and “gamy” means fusion. Therefore the word “karyogamy” refers to the fusion of nuclei. In the sexual cycle of fungus to form spores, plasmogamy is followed by karyogamy and then by meiosis.

Diploid cell refers to the cells with two set of chromosomes. Haploid cells refer to the cells that have only a single set of chromosomes. The number of chromosomes in a haploid cell is half that of a diploid cell. Germ cells are haploid.
