What are Stipules?
Stipules are small, leaf-like structures that can be found at the base of a leaf stalk in many plants. They are often paired, coming in sets of two, and are located where the leaf attaches to the stem. Stipules can vary greatly in shape, size, and texture depending on the plant species. Stipules are considered to be modified leaf parts and serve various functions in plants.
Types of Stipules
There are three main types of stipules: free stipules, adnate stipules, and interpetiolar stipules. Free stipules are not attached to the petiole or stem and are distinct from the leaf. Adnate stipules are fused to the petiole or leaf stalk. Interpetiolar stipules are located between the opposite leaves on a stem. Each type of stipule plays a role in protecting the leaf bud at its base, providing support, or even helping with plant identification.
Functions of Stipules
Stipules serve several important functions in plants. One of the primary functions is to protect the leaf bud in its early stages of growth. Stipules can also provide structural support to the leaf as it develops. In some cases, stipules are modified into thorns or glands, serving as a defense mechanism against herbivores or helping with water conservation. Additionally, stipules can assist in plant identification by varying in shape, size, and color from species to species.
Notable Examples
Various plant species exhibit unique stipule characteristics. For example, pea plants have leaf-like stipules that are modified into tendrils, aiding in climbing and support. The okra plant has distinctive stipules that are large and cup-shaped, surrounding the stem at each leaf node. Some plants have stipules that are so small and inconspicuous that they may go unnoticed without close inspection.
Overall, stipules play a crucial role in the growth and development of many plant species. Their diverse forms and functions contribute to the overall health and vitality of plants in ecosystems around the world.
