Question

Fungi show extracellular digestion but they don't have an alimentary canal as in humans so how?

Answer 1

Agrobios feed by discharging chemicals through the cell layer onto the food in an interaction known as extracellular phototropic digestion. Catalysts catalyse the assimilation of food into atoms that are small enough to be taken up by uninvolved dispersion, transport, osmotrophic, or phagocytosis. Because processing occurs outside of the cell, it is thought to be extracellular. It can occur in the lumen of the stomach-related framework, a gastric hole, or another stomach-related organ, or completely outside the body.

Complete answer:
Despite the fact that fungi lack a stomach-related parcel like humans, they use extracellular absorption. Supplements obtained from separating the substrate on which growths and other decomposers develop are used by growths and other decomposers. The hydra, or ocean anemone, is another example of extracellular assimilation in action. A massive pit known as the gastrovascular hole fills the creature's focal point, with one opening for both food and waste. When unwary prey swim into the opening, stinging cells kill them. The hydra's limbs propel the prey deeper into the hole, where catalysts are emitted to separate the food. When food is processed extracellularly into supplements.
Fungi, unlike humans, do not have a digestive tract and instead rely on extracellular digestion. Fungi are heterotrophic species that feed on other heterotrophic organisms. To sustain their growth and reproduction, they rely on extracellular sources of organic matter. Simple sugars, complex carbohydrates, and polypeptides are examples of extracellular energy sources. They do this with the assistance of their walls.

Note:
Chemicals are synthesised near the hyphal tip. Some are bundled in vesicles associated with the Golgi and then transported to the hyphal tip. At the tip, the substance is delivered. Few compounds are effectively discharged through the plasma layer, where they diffuse or act in the cell divider. It should be noted that the proteins delivered from the hyphal tip require a fluid environment for discharge and subsequent degradative movement.
