Answer:
1. anthers
In angiosperms, pollen is produced by the anthers of the stamens in flowers. In gymnosperms, it is formed in the microsporophylls of the microstrobili (male pollen cones). Pollen consists of one or more vegetative cells and a reproductive cell.
2. pollen
Inside the pollen are two (or, at most, three) cells that comprise the male gametophyte. The tube cell (also referred to as the tube nucleus) develops into the pollen tube. The germ cell divides by mitosis to produce two sperm cells. Division of the germ cell can occur before or after pollination.
