Detailed explanation-1: -Phyllotaxy is the pattern of arrangement of leaves on the stem. It is of three types. Alternate: A single leaf arise at each node. E.g. China rose, sunflower, etc. Opposite: A pair of leaves arise at each node, opposite to each other.

Detailed explanation-2: -The arrangement of leaves on a stem is known as phyllotaxy. Based on the phyllotaxy, leaves can be classified as either alternate, opposite, or whorled.

Detailed explanation-3: -Phyllotaxy is the arrangement of leaves around the stem. One leaf attached per node; leaves may be spirally arranged around the stem (left) or distichous–arranged in two opposite ranks (right). Two leaves are borne at each node on opposite sides of the stem. More than two leaves are at each node.

Detailed explanation-4: -Phyllotaxy is the term used to describe the arrangement of leaves around the stem. The proper arrangement of leaves is important for providing sunlight and photosynthesis. Leaves arise from the node of the stem. They develop from the shoot apical meristems.

Detailed explanation-5: -Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. It is of three types, alternate, opposite, and 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.
