Question

what is the role of pollen tube in spermopsids​

Answer 1

Pollen tube formation is important for séxuaI reproduction to occur in seed plants. Pollen tubes act as conduits to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

Explanation:

The pollen tube grows along the surface of the ovule's funiculus, through the micropyle, and into the female gametophyte. After the pollen tube enters the female gametophyte, it ruptures and releases two sperm cells with its contents.
