General Science question from Laboratory Attendant exam, 2026 by JKSSB
Which term best describes the mode of nutrition in both yeast and mushrooms?
Last updated Jun 18, 2026
Correct Answer:
Option A —
Saprophytic
Here is a quick look at why this term perfectly describes both organisms:
What it means: Saprophytic nutrition is a type of heterotrophic nutrition where organisms feed on dead and decaying organic matter.
How it works: Both yeast and mushrooms belong to the Kingdom Fungi. Since they lack chlorophyll, they cannot perform photosynthesis (ruling out Autotrophic). Instead, they release digestive enzymes directly onto dead organic matter outside their bodies to break it down, and then they absorb the soluble nutrients.
Why the other options are incorrect:
B) Autotrophic: Organisms (like green plants) manufacture their own food using sunlight, water, and carbon dioxide.
C) Parasitic: Organisms live on or inside a living host organism and derive nutrients at the expense of the host (e.g., tapeworms or leeches).
D) Holozoic: Organisms ingest solid organic matter, which is then digested and absorbed inside their bodies (e.g., humans, amoebas).
