Question

Which one of the following terminology does NOT represent the seed dispersal mechanism in crops/plants ?

• A. Autochory
• B. Hydrochory
• C. Zerochory
• D. Zoochory

Hint:

All valid scientific terms for seed dispersal end with the suffix "-chory" (from Greek *khoreia* meaning dance/spread) combined with the agent:
- *Auto-* (self) $\rightarrow$ Autochory.
- *Hydro-* (water) $\rightarrow$ Hydrochory.
- *Zoo-* (animal) $\rightarrow$ Zoochory.
- *Anemo-* (wind) $\rightarrow$ Anemochory.
"Zerochory" is a fabricated distractor.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Seed dispersal is the ecological mechanism by which plant seeds are transported away from the parent plant to minimize competition and colonize new habitats.
Scientific terminology classifies these mechanisms based on the agent of dispersal, utilizing the suffix "-chory."

Step 2: Detailed Explanation:
Let us define the scientific terms associated with seed dispersal:
- (A) Autochory: This is a valid term.
It refers to self-dispersal or active explosive mechanisms where the plant itself shoots or flings seeds away (for example, the explosive pods of *Impatiens* or *Geranium*).
- (B) Hydrochory: This is a valid term.
It refers to seed dispersal facilitated by water currents (for example, the buoyant fruits of coconut or water lilies).
- (D) Zoochory: This is a valid term.
It refers to seed dispersal facilitated by animals, either externally via hooks/barbs (epizoochory) or internally through digestion of edible fruits (endozoochory).
- (C) Zerochory: This is an incorrect, non-existent scientific term.
There is no recognized seed dispersal mechanism called "zerochory."
Instead, other valid terms include anemochory (by wind) and barochory (by gravity).
Therefore, "Zerochory" is the term that does not represent a seed dispersal mechanism.

Step 3: Final Answer:
The term that does not represent a seed dispersal mechanism is Zerochory.
