Tetrasporophyte - (ANSWER)2N produces tetraspores by meiosis
Isomorphic - (ANSWER)Tetrasporophyte is similar in appearance to gametophyte
Heteromorphic - (ANSWER)Tetrasporophyte and gametophyte differ in
appearance
Trichogamy - (ANSWER)Special oogamy; male gamete nonflagellated spermatium
formed by spermatangium and female gamete carpogonium with an elongated
trichogyne
Trichogyne - (ANSWER)Elongated hair of the female gamete
, 2
Carposporophyte - (ANSWER)2N lives as a parasite on female gametophytes and
produces carpospores
Carpospores - (ANSWER)Formed by the carposporophyte by mitosis and
germinate into a diploid tetrasporophyte
Gonimoblast - (ANSWER)Filaments that produce carposporangia
Pericarp - (ANSWER)1N a protective envelope developed by the cells of the
gonimoblast
Ostiole - (ANSWER)Pore of the pericarp
Cystocarp - (ANSWER)Formed by the pericarp and the gonimoblast (fruiting body)
Carpogonial branch - (ANSWER)A uniseriate branch, two to seven cells long which
bears the terminal carpogonium
Auxiliary cells - (ANSWER)A cell which produces the carposporophyte following
the migration of the diploid zygote
Connecting filaments - (ANSWER)Aseptated filaments through which the zygotic
nucleus is transferred from the carpogonium to the auxiliary cell
