Hard bast (bundle cap) occurs in
Hard bast is the patch of sclerenchyma present on outside of each vascular bundle, thereby forming a bundle cap over each bundle. They serve to provide additional mechanical support to the stem and are present in Sunflower stem. Wheat stem represent a monocot stem in which each vascular bundle is surrounded by thick walled bundle sheath, they do not have hard bust. Root is marked by presence of primary xylem and phloem in different radii, separated from each other.
Therefore, the correct answer is option A.
The transverse section of a plant shows following anatomical features: (a) Large number of scattered vascular bundles surrounded by bundle sheath (b) Large conspicuous parenchymatous ground tissue (c) Vascular bundles conjoint and closed (d) Phloem parenchyma absent Identify the category of plant and its part :
