Solution
The correct option is B Siphonogamy
Siphonogamy is a condition in plants in which pollen tubes are developed for the transfer of the male cells to the eggs. The seed plants are siphonogamous, while in the lower plants the male cells usually swim to the eggs. As a consequence, the spermatophytes are called as siphonogamous by some botanists. Syngamy is the fusion of gametes resulting in the formation of a zygote, which develops into a new organism. Porogamy is the entrance of the pollen tube in a seed plant through the micropyle. Chalazogamy is a process of fertilization in which the pollen tube penetrates to the embryo sac through the tissue of the chalaza. Therefore, the correct answer is option B.
