Detailed explanation-1: -Vascular bundles in a dicot leaf are conjoint, collateral, and closed. They are present within the mesophyll tissue which represents the midrib and veins of a leaf.

Detailed explanation-2: -Dicot plants have dorsiventral leaves, which have a clear dorsal or upper surface with thicker cuticle and few or no stomata, compared to the lower surface. Monocot plants, on the other hand, have isobilateral leaves, with stomata on both surfaces, and equal thickness of cuticle on both surfaces as well.

Detailed explanation-3: -Dicotyledons or Dicot is generally referred to the flowering plants or angiosperms in which the seeds typically contain two embryonic leaves or cotyledon. All legumes, including beans, lentils, pea, and peanuts are the best examples of dicotyledons.

Detailed explanation-4: -In monocot and dicot leaves, vascular bundles are surrounded by one or more layers of parenchyma cells known as bundle sheaths. They protect the “veins” of the leaf. In monocot leaves, the cells of the bundle sheath carry out photosynthesis, but this isn’t always the case in dicot leaves.
