Conifers which gametophyte

[Aloha]

Hi all

I need to solve following question:
Describe which gametophyte is produced in the sporangia on the microsporophyll on a conifer pollen cone?
I´m quite sure it´s the male microgametophyte but I know that is not enough to solve the question. What else could I write to describe it?
If someone got an idea I would be very pleased
Thanx
Aloha

I am not sure about the translations:
Ok, so you got the male flower. This This has microsporophiles with microsporanges. These produce microspores- pollen. Each of these microspores is formed of of 2 protalian cells, 1 vegetative cell and one generative cell(4 cells in total). The prothallian cells and the vegetative cell make up the prothallium which is the gametophyte.
