When matching plant anatomical features, focus on unique characteristics:
\begin{itemize}
\item \textbf{Roots:} Monocot roots have polyarch xylem; dicot roots have diarch to hexarch xylem.
\item \textbf{Stems:} Monocot stems have scattered vascular bundles; dicot stems have vascular bundles arranged in a ring.
\item \textbf{Specialized cells:} Bulliform cells are found in monocot leaves; cork cells have suberin deposition.
\end{itemize}
Step 1: Match A) Polyarch xylem
Polyarch xylem refers to a condition where there are many (more than six) protoxylem strands. This arrangement is characteristic of Monocot roots. In dicot roots, the xylem is typically diarch to hexarch.
So, A $\rightarrow$ III. Monocot root.
Step 2: Match B) Colourless cells in epidermis
Colourless (or empty) cells in the epidermis, specifically large, empty, and colorless epidermal cells, are known as Bulliform cells. These are typically found in the epidermis of monocot leaves (especially grasses) and help in the rolling and unrolling of leaves in response to water availability.
So, B $\rightarrow$ I. Bulliform cells.
Step 3: Match C) Ring arrangement of vascular bundles
The arrangement of vascular bundles in a ring is a characteristic feature of Dicot stems. In dicot stems, the vascular bundles are arranged in a specific ring, with cambium present between xylem and phloem, allowing for secondary growth. In contrast, monocot stems have scattered vascular bundles.
So, C $\rightarrow$ IV. Dicot stem.
Step 4: Match D) Suberin deposition on cell wall
Suberin is a waxy, water-repellent substance that is deposited on the cell walls of certain plant cells, making them impermeable to water and gases. This deposition is characteristic of Cork cells (phellem), which are part of the periderm and provide protection to the plant. It's also found in the Casparian strips of endodermis, but in the context of cell wall deposition for protection, cork cells are a primary example.
So, D $\rightarrow$ II. Cork cells.
Step 5: Formulate the complete match and check options
Combining the matches from Steps 1, 2, 3, and 4:
A $\rightarrow$ III (Monocot root)
B $\rightarrow$ I (Bulliform cells)
C $\rightarrow$ IV (Dicot stem)
D $\rightarrow$ II (Cork cells)
The correct sequence is A-III, B-I, C-IV, D-II.
Let's check the given options:
% Option
(1) A-IV, B-III, C-I, D-II (Incorrect)
% Option
(2) A-III, B-II, C-I, D-IV (Incorrect)
% Option
(3) A-III, B-I, C-IV, D-II (Matches our derived sequence)
% Option
(4) A-III, B-IV, C-I, D-II (Incorrect)
Therefore, Option (3) is the correct answer.
