In which plants the gametes are better protected: mosses or conifers?

In conifers, gametes are better protected than in mosses. Male gametes – spermine, are formed during the germination of the pollen tube. After pollination, the fertilization process begins. The pollen begins to germinate and forms a long pollen tube. It grows towards archegonia. In it, male gametes are formed – sperm.
For the sexual process, the pine does not need water, and two sperm gradually move to the egg through the pollen tube. The tip of the pollen tube, which has grown to the egg, breaks open and sperm is released. At the same time, one of the spermatozoa fuses with the egg, resulting in a zygote. Pollination and fertilization takes place in female cones and are well protected by their scales.
