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:
Explanation:
The features describe a monocotyledonous stem. In monocots, vascular bundles are numerous and scattered throughout the ground tissue, each bundle is surrounded by a bundle sheath, and the ground tissue is largely parenchymatous. Bundles are conjoint and closed (no cambium), and phloem parenchyma is typically absent around the bundles. These characteristics match NCERT’s description of monocot stems, not roots or dicot stems.
? Did You Know?
In monocot stems, there is no distinct cortex–pith arrangement like in dicot stems, and secondary growth is generally absent.
? NCERT Memory Line:
Monocot stem: scattered vascular bundles, bundle sheath around bundles, no true vascular cambium, parenchymatous ground tissue.
