The epidermis is surrounded by a thick cuticle layer. Just below the cortex, parenchyma covers a large area. Phloem has A type secretory secretory cells. Xylem is composed of sclerenchymatic cells and tracheary elements in vascular bundles. The pith is composed of parenchymatic cells. In the section of the root there are four-five rows of periderm. Below this tissue there is cortex parenchyma with intercellular spaces. Inward, there are phloem and xylem tissues. The pith consists of parenchymatic cells. Leaf mesophyll layer has palisade parenchyma on both surfaces. Leaf is equifacial. Collenchyma tissue is in four-five rows on the upper and lower surfaces of the middle vein. The leaf is amphistomatic. Stomata belong to anisocytic types.
