WHAT'S THE FUNCTION OF STIPULES .......????????
Stipules are the lateral appendages which are found attached at the base of the leaf. They protect the leaf in its bud stage.
They are modified in various structures to perform functions accordingly:-
Stipules which are modified into leaves help in photosynthesis to synthesize food.
Stipules which are modified into spines serve the purpose of protection of plants. e.g.- Zizyphus
Stipules can also help the plant in climbing when modified as tendril.eg- Smilax
I think ,Main function of these structures is to protect the leaf in the bud. When green these synthesize food also.They can also work as assimilation organs or can be developed as spines or glands. In pinnate leaves with basipetal segmentation the stipules often have finished their growth whereas the segmentation of the lamina still is progressing
hope it will help u..........thank u............
