Question

Identify the labels correctly in the given diagram.

• A. x - DNA, y - inner membrane, z - stroma lamellae
• B. x - stroma lamellae, y - inner membrane, z - DNA
• C. x - DNA, y - stroma lamellae, z - inner membrane
• D. x - inner membrane, y - stroma lamellae, z - DNA

Hint:

The stroma contains DNA in chloroplasts, and the stroma lamellae connect thylakoid membranes, while the inner membrane surrounds the entire chloroplast.

Answer 1

The Correct Option is C

Step 1: Understanding the components in the diagram.
The diagram likely represents the structure of a chloroplast, and the labels are related to different components of the chloroplast. The DNA is found in the stroma, the stroma lamellae are structures connecting the thylakoid membranes, and the inner membrane surrounds the stroma.
Step 2: Analyzing the options.
(A) x - DNA, y - inner membrane, z - stroma lamellae: Incorrect — The stroma lamellae are not at the position marked by "z."
(B) x - stroma lamellae, y - inner membrane, z - DNA: Incorrect — The "x" position should correspond to DNA, not stroma lamellae.
(C) x - DNA, y - stroma lamellae, z - inner membrane: Correct — The "x" label should correspond to DNA, the "y" label to the stroma lamellae, and the "z" label to the inner membrane.
(D) x - inner membrane, y - stroma lamellae, z - DNA: Incorrect — The "x" position is not the inner membrane.
Step 3: Conclusion.
The correct answer is (C) x - DNA, y - stroma lamellae, z - inner membrane.
