Answer» Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. It is divided into three types: Alternate, opposite and whorled phyllotaxy. (a) Alternate phyllotaxy: In this type, a single leaf arises at each node in alternate manner. E.g. China rose, mustard and sun flower plants. (b) Opposite phyllotaxy: Plants with opposite phyllotaxy have two leaves arising from the node in opposite directions. E.g. Calotropis and guava plants (c) Whorled phyllotaxy: Plants with whorled phyllotaxy have three or more leaves arising from the node, which form a whorl. E.g. Alstonia.
