Question

Choose the right option based on the diagram: 1) Stomatal aperture, 2) Guard cells, 3) Subsidiary cells, 4) Chloroplast

• A. A-1, B-2, C-3, D-4
• B. A-2, B-3, C-1
• C. A-3, B-1, C-2
• D. A-2, B-1, C-3

Hint:

\[ \boxed{\text{Guard cells are kidney-shaped and contain chloroplasts}} \]

Answer 1

The Correct Option is A

Concept: A stomatal apparatus consists of guard cells, stomatal pore, subsidiary cells, and chloroplasts.

Step 1: Identify components.
\[ \boxed{ \text{Stomatal aperture → pore} } \] \[ \boxed{ \text{Guard cells → regulate opening/closing} } \] \[ \boxed{ \text{Subsidiary cells → support cells} } \] \[ \boxed{ \text{Chloroplast → present in guard cells} } \]

Step 2: Match correctly.
Correct identification gives: \[ A \rightarrow 1,\quad B \rightarrow 2,\quad C \rightarrow 3,\quad D \rightarrow 4 \]

Step 3: Select option.
\[ \boxed{\textbf{Option (A)}} \]
