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: -Arrangement of leaves on the stem branches is called as phyllotaxy.

Detailed explanation-5: -Phyllotaxy is the pattern or arrangement of leaves on the stem or branch of a plant. Alternate, whorled, and opposite are the three kinds of phyllotaxy. In alternate phyllotaxy, individual leaves arise from each node on the stem of the plant. Example: sunflower, peepal, mustard, etc.
