Seed Plants. The sporophyte is also the dominant generation in seed plants. Seed plants are vascular plants that produce seeds and include some nonflowering plants (like pine trees) and flowering plants (like oak trees and roses). So when you see any of these plants, you are looking at the sporophyte. sporophyte is created by sexual reproduction of the gametophyte generation. Gametophytes make haploid unicellular gametes, or sperm and eggs. When a sperm cell fuses with an egg cell this is called fertilization. It creates a unicellular diploid zygote.
The spore capsule, often with a supporting stalk (called a seta), is the sporophyte and this grows from the gametophyte stage. You will commonly see the statement that a moss gametophyte consists of leaves on stems. That statement is so close to the whole truth that it's no surprise it's so commonly used.When a moss spore germinates it first develops a protonema.This is a filamentous to sheet-like growth form, often with a strong resemblance to an algal colony or a fern prothallus. In due course one or more stems grow from the protonema and leaves develop on the stems, giving rise to one or more leafy-stemmed plants.ou will commonly see the statement that a moss gametophyte consists of leaves on stems.
