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 can be alternate, opposite or whorled based on where the nodes are present on the stem. The arrangement of leaves on the stem is termed phyllotaxy.

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -5.3.3 Phyllotaxy Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. This is usually of three types – alternate, opposite and whorled (Figure 5.9). In alternate type of phyllotaxy, a single leaf arises at each node in alternate manner, as in china rose, mustard and sun flower plants.
