Hoarseness is a harsh, rough, raspy quality to the voice. Hoarseness is generally caused by irritation of, or injury to, the vocal cords. This trauma to the vocal cords leads to a change in the pitch of the voice. The voice box, or larynx, is the portion of the respiratory (breathing) tract containing the vocal cords that produce sound.
The gametophytes in seed plants, like pine trees and oak trees, are unisexual and microscopic. They are found inside part of the sporophyte and rely completely on the sporophyte for nutrients. For example, in a pine tree, the male gametophyte that produces sperm is found inside a pollen grain.lternation of generations is a type of life cycle found in all plants and some algae species. This process involves a multicellular diploid generation called a sporophyte and a multicellular haploid generation called a gametophyte.
The ovules are the female gametophyte. In gymnosperms, pollination is the transfer of pollen from a microsporangiate, or male cone, to the micropyle of a megasporangiate, or female cone. Once fertilized the female cone produces the seed. Source(s): Conifer cones: http://en.wikipedia.org/wiki/Strobilus#C... just now. Report Abuse. The gametophyte is the male part or male for the term gamete. & sporophyte is the female part or female for the term sporo. From the pine tree, you could only specify the difference of the pines by their cones.
