The deficiencies of micronutrients, not only affects growth of plants

1.	The deficiencies of micronutrients, not only affects growth of plants but also vital functions such s photosynthetic and mitochondrial electron flow. Among the list given below, which group of these elements shall affect most, both photosynthetic and mitochondrial electron transportA. Cu, Mn, FeB. Co, Ni, MoC. Mn, Co, CaD. Ca, K, Na
Answer» Cu-Copper takes part in electron as plastocyanon (between `PS II and PSI`) and cytochrome to oxygen Mg-Mangenese is activator of a number of enzymes like reductases, oxidases, etc. taking part in respiration and photosynthesis Fe- Iron is component of `e^(-)` transferring biomolecules like cytochromes and ferredoxin. they are essential components of photosynthesis.
