Question

Explain with suitable examples the different types of phyllotaxy?​

Answer 1

Answer:

Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. It is of three types:

                   1) alternate,

                   2)opposite and

                   3)whorled phyllotaxy.

In alternate phyllotaxy, a single leaf arises from the node of a branch. This type of phyllotaxy is observed in the sunflower, mustard, and peepal. Plants with opposite phyllotaxy have two leaves arising from the node in opposite directions. It is found in guava and jamunplants. Plants with whorled phyllotaxy have three or more leaves arising from the node. It is found in Alstonia.

Answer 2

Answer:

Phyllotaxy refers to the pattern of arrangement of leaves on the stem or branch. It is of three types - alternate, opposite and whorled.

1: Alternate phyllotaxy: Presence of single leaf at each node in alternate manner is called as alternate phyllotaxy. Example: china rose and ivy.

2: Opposite phyllotaxy: Presence of pair of leaves at each node which are arranged opposite to each other is called as opposite phyllotaxy. Example: guava plant and periwinkle

3: Whorled phyllotaxy: Presence of more than two leaves at each node to make a whorl like pattern gives whorled phyllotaxy. Example: Alastonia and sweet woodruff.
