Calcium

Vedclass · Answer

(D) The deficiency of $Calcium$ $(Ca^{2+})$ leads to the weakening of the pedicel and petiole. $Calcium$ is essential for the formation of the middle lamella in the cell wall, which acts as a cementing material between adjacent cells. When $Calcium$ is deficient, the cell walls become weak, leading to the structural instability of plant parts like the pedicel (flower stalk) and petiole (leaf stalk).
