Question

Why is the large surface area of the mycelium essential for nutrient acquisition by fungi? 

Step-by-Step Solution

Answer

Large surface area of the mycelium essential for nutrient acquisition by fungi because having a large surface area increases the amount of digested molecules that are captured by the fungi. 

Step1. Introduction

Fungi are eukaryotes, and as such, have a complex cellular organization. Fungal cells contain a membrane-bound nucleus. 

Mycelium:- mass of fungal hyphae 

Step2. Explanation

Fungi break down decaying matter in their environment to serve as their food source. Since the digestion occurs externally, the large mycelium can secrete exoenzymes over a large area. The fungi must be able to absorb the small molecules released by digestion, so having a large surface area increases the amount of digested molecules that are captured by the fungi.
