How can seeds be dispersed from the parent plant?

How can seeds be dispersed from the parent plant?

• A. By wind, water, animals, or mechanical means
• B. By photosynthesis
• C. By gravity only
• D. By evaporation

Answer: (A)

Seeds spread away from the parent plant by being carried by wind, floated by water, carried by animals, or released by the plant’s own mechanical actions. Wind dispersal uses light seeds with wings or fluff that catch air; water dispersal relies on seeds that can float and travel with currents; animal dispersal happens when seeds are eaten and later deposited in feces, or when seeds cling to fur or feathers and are carried to new places; mechanical dispersal occurs when seed pods dry out and burst, flinging seeds away from the plant. This mix of methods helps plants reach new areas and reduces crowding with the parent plant. Other ideas don’t describe how seeds move: photosynthesis is how plants make food, gravity alone mostly keeps seeds near the parent, and evaporation is just a change of state, not a way seeds travel.
