Question

what is the correct pair?
a)parasitic fungi-feed on plants and animals
b)saprotrophic fungi-feed on dead and decaying organic matter
c)symbotic fungi-mycorrhiza
d)all of above true
​

Answer 1

Answer:

Saprophytes- Decomposition of dead organic materials

Parasites - Grow on/in living plants and animals

Lichens - Symbiotic association of algae and fungi

Mycorrhiza - Symbiotic association of fungi with plant roots.

So, the correct answer is 'a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)'

Answer 2

Answer:

The correct option is d) all of the above true.

Explanation:

a) parasitic fungi- feeding on plants and animals is Correct as they belong to the most pathogenic group of fungi which invades the plants and animals and obtain nourishment from their host and thereby feeding on their host slowly.

b) saprotrophic fungi- feed on the dead and decaying organic matter is Correct. These fungi are extremely valuable in soil formation as they secrete digestive enzymes which break complex organic matter into simple inorganic molecules. These inorganic molecules are directly absorbed through the cell membrane of the organisms.

c) symbiotic fungi- mycorrhiza is Correct. Mycorrhiza is a symbiotic association between fungal hyphae and roots of higher plants. The roots provide essential nutrients for the growth of the fungi and in return, the fungal hyphae increase the absorbance of water and nutrients that the plant obtains from the surrounding soil.

Hence, all the options given are Correct.
