Grafting is not attempted in monocots because: (IGKV CET Horti 2022)

✅Explanation:
-Grafting, a technique of joining plant tissues from different plants to create a new combined plant, relies on the presence of a specific tissue called cambium for successful fusion and growth. This meristematic tissue, found in dicots and gymnosperms, is responsible for secondary growth in plants, producing new phloem and xylem tissues. In monocots, however, cambium is absent. Their vascular bundles are scattered throughout the stem, and they lack the secondary growth mechanism present in dicots. This makes it nearly impossible to achieve the necessary tissue alignment and connection required for successful grafting in monocots.

📌 Other Options:
-(A) Vascular bundles are scattered: While the scattered arrangement of vascular bundles in monocots might pose challenges for grafting compared to the more organized arrangement in dicots.
-(C) Absence of endodermis: The endodermis is a single layer of cells surrounding the vascular tissue in plants.
-(D) Sclerenchymatous hypodermis: The sclerenchymatous hypodermis is a layer of thick-walled supporting tissue found in some plants.
