SOLUTIONS/GET IT 100% ACCURATE
Triphasic -CORRECTANSWER Alteration of generations
A) tetrasporophyte 2N
B) Gametophyte 1N
C) Carposporophyte 2N
Tetrasporophyte -CORRECTANSWER 2N produces tetraspores by meiosis
Isomorphic -CORRECTANSWER Tetrasporophyte is similar in appearance to
gametophyte
Heteromorphic -CORRECTANSWER Tetrasporophyte and gametophyte differ in
appearance
Trichogamy -CORRECTANSWER Special oogamy; male gamete nonflagellated
spermatium formed by spermatangium and female gamete carpogonium with an
elongated trichogyne
Trichogyne -CORRECTANSWER Elongated hair of the female gamete
, Carposporophyte -CORRECTANSWER 2N lives as a parasite on female gametophytes
and produces carpospores
Carpospores -CORRECTANSWER Formed by the carposporophyte by mitosis and
germinate into a diploid tetrasporophyte

Pericarp -CORRECTANSWER 1N a protective envelope developed by the cells of the
gonimoblast
Ostiole -CORRECTANSWER Pore of the pericarp
Cystocarp -CORRECTANSWER Formed by the pericarp and the gonimoblast (fruiting
body)
Carpogonial branch -CORRECTANSWER A uniseriate branch, two to seven cells long
which bears the terminal carpogonium
Auxiliary cells -CORRECTANSWER A cell which produces the carposporophyte
following the migration of the diploid zygote
