Question

Ruellia seeds are dispersed by

• A. Animals
• B. Water
• C. Wind
• D. Explosion of fruit

Answer 1

Answer: (D)

Explosion of fruit

Some plants disperse their seeds forcefully by ejecting them. This type of seed dispersal occurs when the tension/pressure inside the fruit is great and the fruit splits open. The walls of the fruit spring back, flinging the seeds out with force. Some plants belonging to the family of Fabaceae, Euphorbiaceae, Acanthaceae and Malvaceae disperse their seeds by explosion of the fruit.

Examples of such plants include Lupins (Lupinus spp.), Bitterbark (Petalostigma spp.), Mexican petunia (Ruellia spp.), vegetable okra (Abelmoschus spp.), etc.

So, the answer is D.
