NEET BIOLOGY

Detailed explanation-1: -In monocot leaf, mesophyll cells are not differentiated into palisade and spongy tissues . But there is well differentiate mesophyll cells in dicot stem. Also in the upper epidermis, there are some large cells found in groups which are called bulliform cells. The venation pattern in monocot is parallel.

Detailed explanation-2: -In dicot leaf, the mesophyll is made of two types of parenchyma cells. palisade and spongy. This differentiation is not seen in the mesophyll of the monocot leaf. Here the mesophyll is made of similar sized cells.

Detailed explanation-3: -In monocot leaves or isobilateral leaves, undifferentiated mesophyll is present that shows spongy parenchyma. So, the correct answer is ‘Dicot leaves’. Additional information:-Stems of dicot plants have a well-defined epidermis with a cuticle, a layer of dermis along with multicellular stem hair.

Detailed explanation-4: -Monocot leaves are parallel venation in maize leaf and show its own structure and its transverse section passing through a midrib region. In monocot leaf epidermis are in two layers on each surface of the leaf epidermal layers are made of compactly arranged and shape ate in barrel-shaped cells.

Detailed explanation-5: -In monocots, spongy parenchyma represents the only cell type found in the mesophyll. Unlike the palisade parenchyma, the spongy parenchyma possesses an irregular arrangement with large spaces in between each cell.
