Answer:
(d) The reproductive organs in the members of
Cryptogams (seedless plants), i.e., thallophyta, bryophyta and pteridophyta are
inconspicuous or hidden. They producs naked embryos after fertilization (union
of male gamete with female gamete) that are called spores.
In the case of phanerogams (seed bearing plants), i.e.,
the gymnosperms and angiosperms, seeds are produced after fertilization. They
contain embryo along with stored food. The stored food provides nourishment to
the developing embryo.
Gymmosperms bear naked seeds while the angiosperm bears
seeds enclosed in a fruit (the ovules are inside the ovary).
