Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Fungi use hyphae to obtain water and nutrients. Which of the following indicates why this is necessary?
A
Fungi are multi-celled organisms.
B
Fungi grow in response to light
C
Fungi grow away from gravity
D
Fungi lack a root system.
Explanation: 

Detailed explanation-1: -Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic: they rely solely on carbon obtained from other organisms for their metabolism and nutrition.

Detailed explanation-2: -Hyphae absorb nutrients from the environment and transport them to other parts of the thallus (fungus body). Finally, they may become bound together or modified to form more complex structures.

Detailed explanation-3: -To feed, both types of fungi secrete digestive enzymes into the nutritive surface on which they are growing. The enzymes break down carbohydrates and proteins, which are then absorbed through the walls of the hyphae.

Detailed explanation-4: -Collectively, hyphae are referred to as mycelium (mushroom “roots”), which form the main, life-sustaining part of the fungus. These hyphae secrete enzymes that help break down the rotting wood, leaves, and other organic debris, liberating nutrients that are not readily accessible to other life forms.
