The megagametophytes of endosporic plants such as the seed ferns developed within the sporangia.

Aug 24, Inside female cones, female spores develop into female gametophytes. Each female gametophyte produces an egg inside an ovule. Pollination occurs when pollen is transferred from a male to female cone. If sperm then travel from the pollen to an. Sporophyte, in plants and certain algae, the nonsexual phase (or an individual representing the phase) in the alternation of generations - a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other.

The sexual phase is the treeclear.barg: fall tree. Sporophyte stage is asexual, sneller stump grinder for sale gametophyte stage is sexual.

The haploid spores produced will then form the next gametophyte generation by growing into multicellular haploid individuals called gametophyte.

The first cell in a sporophyte generation is the diploid zygote, while the first cell in the gametophyte stage is the haploid spore.

In the sporophyte phase, haploid spores are formed and in the gametophyte phase, diploid male and female gametes are treeclear.barted Reading Time: 5 mins. Life Cycle of a Conifer Pine trees are conifers (coniferous = cone bearing) and carry both male and female sporophylls on the same mature sporophyte.

Therefore, they are monoecious plants.

We learned above that the zygote or fertilized cell is diploid; however, the spores formed by them are haploid.

Like all gymnosperms, pines are heterosporous and generate two different types of spores (male microspores and female megaspores). A sporophyte (/ s p ɔː r oʊ ˌ f aɪ t /) is the diploid multicellular stage in the life cycle of a plant or treeclear.bar develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each treeclear.bar land plants, and most multicellular algae, have life cycles in which a multicellular Estimated Reading Time: 5 mins.
