adult sporophyte - White Mature Milf in an Adult Theater


In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and embryo sac Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. Apr 28,  · A gametophyte represents the sexual phase of the plant life. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation.

Kelps disperse through motile zoospores, which are released from the adult sporophyte (Fig. ) in very high density (e.g., a single individual of Ecklonia maxima in South Africa releases > 30 billion zoospores per year, Joska & Bolton, ). The sporophyte produces spores during meiosis which decreases the number of chromosomes by half (n/2). These spores are now responsible for the development of gametophyte. In mosses, the adult sporophyte depends on the gametophyte for its nutrition. The embryo sporophyte develops in a female sex organ called archegonium.

They are only dependant on the gametophyte in very early stages, and the adult sporophyte have roots, stem, leaves, a vascular system, and several kinds of sporangia. We all cultivate ferns for their sporophytes. Gymnosperms and Angiosperms have sporophytes that are completely independent from the gametophytes.
