Solar Energy

The tiny section of the sun's strength that reaches the earth in a single yr is nearly 10,000 instances the power intake of humankind in the course of that very same interval. Absorbed within the surroundings and at the floor of the earth, it truly is accountable for the temperature diversity that permits our varied ecosystems to exist, and in addition for a good portion of the on hand renewable and fossil power provides.

The role of Ca+ 2 in rhizoid and repair shoot cell growth is under investigation. Thus Griffithsia rhizoids and repair shoot cells are a good model for studying cytoplasmic localization and localized growth. We have found that transcellular ion currents per se do not appear to regulate growth in these cells. K+, as a osmotic solute, is necessary for continued elongation. Nigericin and monensin have 49 dramatic and similar effects on growth and morphogenesis in all cells of Griffithsia. While the mechanism of action of these ionophores is not known at this time.

Cell division occurs by binary fission parallel to the valvar plane.

At 30 min the dramatic swelling has increased. Cis-cisternae do not appear to swell. Vesicle fusion with the plasmalemma does not appear to occur. ) does not appear to be affected by monensin. , 1980). In these cells, too, monensin appears to affect dictysomes and dictysome-derived vesicles specifically. Preliminary ultrastructural observation of Griffithsia rhizoids, that have been recovering for 24 hrs following monensin treatment, suggests that the enlarged cisternae, produced during monensin treatment may fuse with each other, but do not fuse with the plasmalemma.
