General properties — Fungi are generally not characterized by which of the following traits?

Introduction / Context:
This question checks core biological distinctions between fungi and plants or algae. While fungi share some superficial traits with plants (cell walls, sessile growth), their nutrition and metabolism are different.

Given Data / Assumptions:

• Most fungi are filamentous (multicellular hyphae forming mycelium), though yeasts are unicellular.
• Fungal cell walls contain chitin and glucans.
• Fungi reproduce via spores (sexual and/or asexual).

Concept / Approach:
Fungi are heterotrophs that obtain carbon from organic compounds; they lack chlorophyll and do not perform photosynthesis. Therefore, “photosynthetic” is the trait that generally does not apply to fungi.

Step-by-Step Solution:

Verification / Alternative check:
Microscopy and biochemical assays show absence of chloroplasts and photosynthetic pigments in fungi.

Why Other Options Are Wrong:

• Multicellular: typical of molds.
• Containing cell walls: true (chitinaceous).
• Spore-producing: hallmark of fungal reproduction.

Common Pitfalls:
Confusing fungi with plants due to superficial similarities; fungi are absorptive heterotrophs.

Final Answer:
photosynthetic
