What is pollen produced in a gymnosperms?

In gymnosperms, pollen is produced in the male cones (microstrobili) and consists of microscopic grains that contain the male gametes (sperm cells). These pollen grains are typically wind-dispersed, allowing them to travel to female cones (megasporangiate strobili) for fertilization. Gymnosperm pollen is often characterized by a tough outer wall, which helps protect the gametes during their journey to the ovule. This process is crucial for the reproduction of gymnosperms, which include conifers and cycads.
