Biology Coloring Workbook
These spores germinate to form the next generation, called the gameto- phyte
generation, and cells in the gametophyte generation are also haploid. Male and
female gametes (sex cells) are formed at the end of this generation, and when
male ...

Their substrate is a dark substrate that does not allow light to enter the
gametophyte from the bottom (substrate) side of the gametophyte. Humidity can
vary widely between the substrate side of the gametophyte (higher humidity) and
the air ...
Gametogenesis occurs in them at such an early stage of an extremely
abbreviated ontogeny of the gametophyte that gametangia cannot even be
formed, and the gametes are formed without them. Moreover, the development of
the gametes ...
Zygote (2n) Sporangia (2n) Alternation of gametophyte and sporophyte gener
tions in the plant life cycle (see also Fig. 13-4). In some plants, the gametophyte

Handbook of Plant Science
The male gametophyte in angiosperms is the pollen grain. Male gametophyte
development starts with the anther, when sporogenous initial cells divide to give
rise to a tapetal initial cell and a microspore mother cell. Each tapetal initial cell
will ...

This hypothesis assumes that the free-living branching sporophyte of the
