how many lobes are there in one anther
2 lobes
how many thecae present in one lobe
2 thecas
how many microsporangia present in one anther
4 microsporangiums
the distal end of filament attaches to
anther
the proximal end of filament attaches to
thalamus or petals
two main parts of a typical stamen are
anther and filaments
in typical angiosperm anthers are
bilobed
microsporangium develops into
pollen sacs
how man layers are present in a typical microsporangium
4
layer that nourishing the pollen grains
tapetum
centre of each microsporangium have
sporogenous tissue
