Why does dicot leaf has bundle shealth extension made of parenchyma and in monocot its of schlerenchyma?

Dear student
Please find below the solution to the asked query

In dicots, large vascular bundles are surrounded by the parenchyma and collenchyma cells and form bundle sheath extensions. The parenchyma contain fewer number of chlorophyll molecules and help in photosynthesis while the collenchyma provides them with flexibility. 

In monocots, the sclerenchymatous cells extend from the vascular bundle towards upper and lower epidermis and form bundle sheath extensions. This provides extra support to the vascular bundles and leaves. 


Hope this information will clear your doubts about the topic.
