EMBRYOGENESIS IN PLANTS Flashcards
types of plant propagation
asexual
sexual
artificial
testing the viability of the seed
seed scarification
scratching
rugdoll method
process of initiation and development of an embryo from a zygote or somatic cell
embryogenesis
types of embryogenesis
zygotic
somatic
the physical, observable transition from a nonembryogenic cell to an embryogenic cell in somatic embryogenesis appears to occur when the progenitor cell undergoes an unequal division, resulting in a larger vacuolate cell and a small, densely cytoplasmic cell
initiation of an embryonic cell
involved derivatives of both the basal and apical cells of the two-cell embryo
root apex
determined in an early globular stage before the cell cleavage that delineates the protoderm
shoot apex
during the transition from the globular to the heart stage are the first visible sign of the formation of the two embryonic organ systems
morphological changes
terminal event of embryogenesis
maturation
process of development of plant embryos, being either a sexual or asexual reproductive process that forms new plants
a process that occurs after fertilization of an ovule to produce a fully developed plant embryo
plant embryogenesis
embryogenesis may occur naturally in the plant as a result of sexual fertilization
zygotic embryo
plant cells can also be induced to form embryos in plant tissue culture
somatic embryos
an end stage embryo has five major components
shoot apical meristem
hypocotyl
root meristem
root cap
cotyledons
plants flower many times during their lifetime
polycarpic/iteroparous
characterized by a massive flowering episode which is followed by senescence and death
semelparous
