MIC 121 Characteristics and Structure of Fungi Objective Question

Question

Dimorphic fungi exhibit two forms based on temperature. At 37°C (body temperature), what form do they typically take?
Options
A Filamentous (mould)
B Unicellular (yeast)
Correct Answer
C Sporangiospore
D Mycelial
Correct Answer

Option B is the correct answer.

Detailed Explanation

Dimorphic fungi are characterized by existing in two forms depending on temperature. At 25°C (room temperature), they typically grow as filamentous moulds, while at 37°C (body temperature), they switch to a unicellular yeast form. This is often remembered with the mnemonic: 'Mould in the cold, yeast in the heat'.

Hint

Think about the form that would be most common within a warm host body.
