Produces Spores
Three examples of a sporophyte are Polypodium, mosses, and a pine tree.
In pine trees, the sporophyte generation consists of the adult tree itself, including the roots, trunk, branches, and needles. The sporophyte produces reproductive structures called cones, which contain the spores that will develop into the next generation of gametophytes.
gametophyte as well as sporophyte generation
A pine tree is generally a Sporophyte - a multicellular, diploid, spore-producing organism. However, the created spores are haploid, and thus begin the gametophyte phase, in which the microspores (pollen) and megaspores (female receptors), will combine back into a gamete, and begin the sporophyte stage again. So, the pine tree is mostly sporophyte, but has very small gametophyte parts that create gametes. They're very small, but they're there.

the first cell in sporophytic generation is the zygote
When you see a pine tree, or a spruce, or a cone-bearing shrub, the "main plant" is a sporophyte

A pine tree is a diploid plant. In the life cycle of a pine tree, the sporophyte generation, which is the dominant form, is diploid, containing two sets of chromosomes. It produces haploid spores through meiosis, which develop into the gametophyte generation, but the mature pine tree itself remains diploid.
can produce spores
It is called the Pine Tree State because it has a LOT of pine trees.
Maine's nickname: The Pine Tree State. It is called that because Maine has many pine trees.
