Explain with suitable examples the different types of phyllotaxy.
Phyllotaxy refers to the arrangement of leaves on the stem or branch. The three types are: Alternate phyllotaxy, where a single leaf grows at each node in an alternate manner, as in sunflower; Opposite phyllotaxy, where a pair of leaves arises at each node and lie opposite to each other, as in guava; Whorled phyllotaxy, where more than two leaves arise at a node and form a whorl, as in Alstonia.
