Vedclass · Answer

(B) Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. In distichous phyllotaxy,the leaves are arranged in two vertical rows on opposite sides of the stem. The fraction $1/2$ indicates that the leaves are separated by an angle of $180^o$ (half of a circle). This means that the $3^{rd}$ leaf is positioned directly above the $1^{st}$ leaf,completing one full cycle of $360^o$ after two leaves. Therefore,the $3^{rd}$ leaf lies on the $1^{st}$ leaf at an angle of $180^o$ relative to the $2^{nd}$ leaf.
