NEET BIOLOGY

Detailed explanation-1: -Metabolism and nutrition Thus, digestion occurs outside of the body. In multicellular fungi, first, exoenzymes are transported out of the hyphae, where they process nutrients in the environment. Then, the smaller molecules produced by this external digestion are absorbed through the large surface area of the mycelium.

Detailed explanation-2: -Fungi secure food through the action of enzymes (biological catalysts) secreted into the surface on which they are growing; the enzymes digest the food, which then is absorbed directly through the hyphal walls.

Detailed explanation-3: -Kingdom Fungi (the true fungi) is a monophyletic group of eukaryotic heterotrophs that reproduce with spores and have chitinous cell walls. The most familiar fungi are kitchen molds and mushrooms. The kingdom may include 1.5 million species, of which about 80, 000 species have been named and described.

Detailed explanation-4: -Generally, plants make their food using the sun’s energy (photosynthesis), while animals eat, then internally digest, their food. Fungi do neither: their mycelium grows into or around the food source, secretes enzymes that digest the food externally, and the mycelium then absorbs the digested nutrients.
