DENDROLOGY

Detailed explanation-1: -In case pollination does not occur, the gametes will not fuse to produce zygote. As a result, fertilisation will not occur.

Detailed explanation-2: -Although pollination is one of the steps necessary for fruit and seed development, fertilization is also necessary. The two terms are often confused and should be distinguished from each other because fertilization does not always follow pollination.

Detailed explanation-3: -After pollination, a male cell (pollen grain) fuses with a female cell in the ovule. This process is called fertilisation and it can usually happen only after pollination takes place. The fertilised ovules then grow into seeds.
