The rachis is an integral part of plant anatomy that carries an important role in a plant structure. It is the elongated main axis of a compound leaf or a fruiting cluster. The rachis of a feather refers to the central shaft, while for plants, it’s responsible for bearing the leaflets or sometimes flowers/fruits in certain plant species. Essentially, rachis plays a pivotal role in supporting and providing structure to these fragile life forms, contributing to the overall stability and growth of plants and feathers alike.#16#
