generative nucleus मीनिंग इन हिंदी

The nucleus of the tube cell has meanwhile passed into the tube, as does also the generative nucleus, which divides ( if it hasn't already ) to form two sperm cells.
During pollen tube growth towards the ovary, the generative nucleus divides to produce two separate sperm nuclei ( haploid number of chromosomes ) a growing pollen tube therefore contains three separate nuclei, two sperm and one tube.
