A contribution to the gametophyte
morphology and development in several species of Thelypteris, Thelypteridaceae.
Response of spores and young gametophytes
of Cyathea delgadii Sternb.
Data of spore germination and gametophyte
development were given in percentages and analyzed with SPSS 20.
In contrast to animals, plant fertilization is based on the interplay between multicellular haploid gametophytes
A new approach to kelp mariculture in Chile: production of free-floating soporophyte seedlings from gametophyte
cultures of Lessonia trabeculata and Macrocystis pyrifera.
(haploid) stage or generation is the dominant form for lower (nonvascular) plants--the sporophyte begins less evident and smaller.
Multicellular and branched hairs on the fern gametophyte
continues growth and produces new sporogonia every year again.
Example: In pine trees, the immature male gametophyte
is a megaspore, the embryonic pine seed, a pollen tube or a pollen grain?
The haploid phase of a plant's life when the sex cells (gametes) are produced.
Genetic variability of gametophyte
growth rate in Maize.
Since red algae lack motile spores, and spermatia must fertilize carpogonia on the female gametophyte
, fertilization success is likely very low (Searles 1980).
