Which statement accurately describes how fungi obtain nutrients or their characteristic structures?
A: All fungi are single-celled organisms that obtain nutrients by photosynthesis.
B: Fungi are heterotrophs that secrete enzymes externally to break down complex molecules, then absorb the smaller nutrients.
C: Mycelia are specialized single-celled structures that absorb light for energy production.
D: Yeasts are multicellular filaments, while hyphae are single-celled organisms.
Explanation
Fungi are heterotrophs and absorb nutrients from their environment. They do this by secreting hydrolytic enzymes into their surroundings to break down complex organic molecules into simpler compounds, which are then absorbed.
