NEET BIOLOGY

Detailed explanation-1: -Parasitic Fungi are fungi that can invade a living host and obtain nourishment, often causing damage to the function and structure of the host.

Detailed explanation-2: -Parasitic fungi feed on living organisms (usually plants), thus causing disease. To feed, both types of fungi secrete digestive enzymes into the nutritive surface on which they are growing.

Detailed explanation-3: -Parasitic and pathogenic fungi form symbiotic relationships with other living organisms, similarly to mycorrhizal fungi; however, they benefit to the detriment (and sometimes death) of their host. Many species affect trees and other plants. Others attack mushrooms, sometimes rendering the host species unrecognizable.

Detailed explanation-4: -Harmful Fungi Some types of fungi produce spores that cause a form of meningitis, an inflammation of tissue surrounding the brain or spinal cord. Five species of molds-aspergillus, fusarium, lomentospora, scedosporium and mucormycetes-have been identified as “killers of humans”.

Detailed explanation-5: -Parasitic fungi are coming in contact with their host plants under the form of motile zoospores, which can digest the root cell wall and penetrate into the cytoplasm, from where they will colonize the whole plant.
