Chloroplast Development in Charophyceae
Members of the Charophyceae are particularly suited to studies on nuclear-chloroplast relationships . The chloroplasts in the elongated internodal cells are arranged in regular rows . Unlike the nuclei and most of the cytoplasm, they are stationary and do not participate in the active streaming of the protoplasm . It is thus possible to maintain plastids in one section of the cell in the dark a...
متن کاملInterpolation of microtubules into cortical arrays during cell elongation and differentiation in roots of Azolla pinnata.
Longitudinal sections of roots of Azolla pinnata R. Br. were prepared for electron microscopy so that cortical microtubules could be counted along the longitudinal walls in cell files in the endodermis, pericycle, and inner and outer cortex, and in sieve and xylem elements. With the exception of the xylem, where there are no transverse cell divisions, each file of cells commences with its initi...
متن کاملAltered nitrogenous pools induced by the azolla-anabaena azolla symbiosis.
The free amino acid and ammonia pools of Azolla caroliniana were analyzed by quantitative column chromatography on columns capable of separating all of the nitrogenous constituents normally found in physiological fluids. Comparisons were made of plants containing symbiotic algae and grown on nitrogen-free media, plants grown on media containing nitrate, and algae-free plants also grown on nitra...
متن کاملAdsorption of Malachite Green Dye from Aqueous Solutions Using Roots of Azolla Filiculoides
