The floral scent of Yucca filamentosa consists mainly of homoterpenes and long-chain aliphatic hydrocarbons, among which DMNT (22) has been identified as the dominant component, and two dioxygenated compounds with … NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. The pistil (female part) of each flower ends in a three-lobed stigma.In order for pollination to occur, masses of pollen must be forced down into this central stigmatic hole. The sharp, sword-like leaves of the Yucca plant provide protection for the eggs, and the seeds of the plant provide a source of food for newly hatched larvae. Active pollination among prodoxids has evolved only once, in the yucca moths.

NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. The pollination mutualism between Yucca plants and yucca moths (Tegeticula and Parategeticula) would seem to be locked into such an obligate mutualism.
