Which statement is true about pseudohyphae?

• A. Regular points of constriction (link sausages) and may bud to form blastospores
• B. Produced only in nutritionally rich environments
• C. They are identical to true hyphae
• D. They lack any constrictions

Answer: (A)

Pseudohyphae form when yeast cells bud but don’t fully separate, so you get a chain of elongated cells with small constrictions at the points where division occurred. That sausage-link appearance, with regular constrictions, is the hallmark. Because the daughter cell can bud off from these constricted sites, the structure can produce blastospores (yeast buds that remain attached or form new buds). This distinguishes pseudohyphae from true hyphae, which are long, continuous filaments with septa but without the characteristic constricted budding sites. Pseudohyphae aren’t limited to nutritionally rich conditions; they can arise under various growth stresses and nutrient conditions, whereas true hyphae are a separate morphogenic form.
