Question

where does the germination of pollen grains takes place and how

Answer 1

HEYA....

It takes place in the stigma of the female flower. Pollen grain divides into 2 cell..

During germination, the tube cell elongates into a pollen tube. In the flower, the pollen tube then grows towards the ovule where it discharges the sperm produced in the pollen grain for fertilization.

 The germinated pollen grain with its two sperm cells is the mature male microgametophyte of these plants.

Answer 2

HEY YOUR ANSWER IS .......


All pollen grain contains vegetative (non-reproductive) cells (only a single cell in mostflowering plants but several in other seed plants) and a generative (reproductive) cell. Inflowering plants the vegetative tube cell produces the pollen tube, and the generative cell divides to form the two sperm cells.

Both gymnosperms (cone-bearing plants) and angiosperms (flowering plants) produce pollen as part of sexual reproduction. In gymnosperms pollen is produced in microsporangiate cones (male cones or pollencones), while in angiosperms pollen is produced in the anthers
