Which photosynthetic process will be last affected by shorter periods of daylight

The Calvin Cycle is the process that will be the last one to be affected by shorter periods of daylight. Carbon dioxide goes in the interior of a leaf through pores of plants, which is called stomata and spreads into the stroma of the chloroplast this is the site of the Calvin cycle reactions, wherein sugar is produced and synthesized. These reactions are also called the light-independent reactions because they are not directly driven by light.

The Calvin Cycle

Explanation:

APEX

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
