Stipules are often referred to as the overlooked components of plant anatomy since they are small and often concealed behind the main leaf.
Stipules can vary in shape and size, and they can be present in different plant species.
Some stipules are tiny and narrow while others can be large and broad in shape.
In some plants, stipules can be absent altogether.
At their simplest, stipules are small leaf-like structures that grow at the base of some leaves on a plant.
They are usually lateral structures- in which they are arranged to the side of the leaf blade- and are attached to the stem.
They hold several functions that are significant to the plant.
Firstly, stipules function as supportive structures to the overall structure of a plant as they add extra support to the leaf.
They may also help in the regeneration of the leaf if it’s damaged.
Secondly, stipules can perform key roles in the protection of the plant.
For some plants, stipules are evolved into thorns or spines that protect them from insects and other animals.
Lastly, stipules can be used for photosynthesis and help the plant to fix and store nutrients, similar to the functions of leaves.
Stipules are, therefore, important structures that every botanist needs to understand to get a better understanding of plant species.
To conclude, stipules might look insignificant and tiny, but they serve significant functions that are essential in the biology of plants.
Understanding them can help in the identification of plant species and aid in the development of agricultural practices that could bring about higher crop yields.
