Arrange the stages of the Scots pine life cycle in the correct order, starting from the germination of the seed.

The first stage of pine development is pollination and fertilization. After that, the scales of the female cones are glued together with pine resin. The second stage is fertilization, which starts in 12-14 months. The pollen will germinate, and a pollen tube will be formed from the vegetative cell. As a result of the fertilization process, a zygote is formed. Then the cone grows, lignifies. Under favorable conditions, the embryo begins to grow rapidly.
1) Development of sporophyte – 2) Formation of male and female cones – 3) Release of pollen – 4) Formation of a pollen tube – 5) Fertilization of an egg – 6) Development of a seed
