Problem 170 - Objective Biology for NEET

Question

Cortex and pith are not distinguished in (a) Dicot stem (b) Monocot stem (c) Dicot root (d) Monocot root

Step-by-Step Solution

Answer

The correct answer is (b) Monocot stem.

Step 1: Understand the Terminology

Make sure you understand what is meant by 'Cortex' and 'Pith'. In the context of plant anatomy, the cortex is the outermost layer of the plant stem or root, while the pith is the central part. Furthermore, comprehend the difference between Dicots and Monocots. Dicots and Monocots are two types of flowering plants, distinguished mainly by the number of seed leaves or cotyledons they possess.

Step 2: Identify where Cortex and Pith are undistinguishable

Now you need to identify in which plant type - Dicot or Monocot, and which part - Stem or root, the Cortex and Pith are undistinguishable. In Monocots, the vascular bundles are scattered and not arranged in a circle. There is no typical distinction between cortex and pith in the monocots as the ground tissue is not separated into cortex and pith.

Step 3: Match the Answer

Compare the facts from step 2 with the given answer choices. The correct option will be where Cortex and Pith are not distinguished.
