Question

Fungi exist as single cells or as branching networks of multicellular filaments. How does the structure of the filaments relate to their function?

A. Their large surface area aids in nutrient absorption.
B. Their large surface area aids in photosynthesis.
C. Their high concentration of mitochondria aids in energy production. D. Their long, branching structure helps fungi find a location to produce offspring

Answer 1

The correct option is A.Their large surface area aids in nutrient absorption.

Step-by-step explanation:

The main parts of a fungi's body include long, branched hair-like projections called the filaments and an outer cell wall; chitin. The hair-like projections are also referred as hyphae. A complex group of filaments or hyphae is termed as mycelium.

As the filaments increase the surface area of fungi, their basic function is to absorb nutrients from external sources. Enzymes for nutrient absorption are released by the filaments on the substrate and hence the nutrients are absorbed.
