D. 4

Explanation

Solution

Fungi or fungus includes rusts, yeasts, smuts, molds, etc. they can either be free living or in symbiotic relationships with animals or plants or animals. The given table contains types of fungus, mode of their reproduction/type of mycelium/mode of nutrition and to which category of fungus they belong.

Complete Answer:
Let us find the correct answer from the following,
Option A : Phytophthora belongs to algal fungi, also known as phycomycetes. These are mostly found in aquatic habitats. They have coenocytic and septate mycelium. Therefore, this is the incorrect option.

Option B : Agaricus, which is also known as mushroom, belongs to basidiomycetes. They grow on soil, logs and tree stumps. Asexual spores are absent, but vegetative reproduction is common in them.These are saprophytic fungi and are not parasitic. Ustillago and Puccinia are other examples for basidiomycetes. Therefore, this is the incorrect option.

Option C : Mucor is a type of fungus seen in soil and plant leaves. They belongs to the category of phycomycetes and they undergoes asexual reproduction by zoospores or aplanospores. Other examples for phycomycetes are Rhizopus and Albugo. Therefore, this is the incorrect option.

Option D : Alternaria belongs to deuteromycetes, which are also known as imperfect fungi, since they reproduce through asexual reproduction or vegetative reproduction. Deuteromycetes reproduces by asexual spores known as conidia. Some members of deuteromycete are parasitic and saprophytes, while a majority of them are decomposers of litter and they help in mineral cycling. Alternaria lack sexual reproduction. Therefore, this is the correct option.

Thus, the correct option is D.

Note: The commercial uses of fungi are- they are used in production of vitamins, glycolipids, etc via fermentation, they are a source of food materials, they are used in baking, wine and beer making, etc.
