Explain with suitable examples the different types of phyllotaxy.
Phyllotaxy refers to the pattern or organization of leaves on a stem or branch. Alternate, whorled and opposite phyllotaxy are the three forms of phyllotaxy. (i). Alternate Phyllotaxy: - In alternate phyllotaxy, a single leaf grows from a branch node. Example: Sunflowers, mustards, and peepal. (ii). Opposite Phyllotaxy: - Plants with opposite phyllotaxy have two leaves that grow from the same node in opposite directions. Example: Guava and Jamun plants. (iii. Whorled Phyllotaxy: - Plants with whorled phyllotaxy have three or more leaves that grow from a single node. Example: Alstonia and Nerium.
