Identifying sclerenchyma cell features in plant stem

Steps:

• Examine photomicrograph: Q shows thick-walled cells typical of sclerenchyma in stems for support.
• Evaluate statement 1: Sclerenchyma walls contain cellulose base reinforced by lignin, with pits for material passage.
• Evaluate statement 2: Plant cells, including sclerenchyma, connect via plasmodesmata for cytoplasm continuity.
• Evaluate statement 3: Likely false, as sclerenchyma cells are alive during development but mature cells lack protoplasts, not matching typical descriptions.

Why A is correct:

• Sclerenchyma definition includes lignified, pitted walls (statement 1) and plasmodesmatal connections (statement 2) per plant cell biology.

Why the others are wrong:

• B includes incorrect statement 3.
• C omits valid statement 2.
• D omits valid statement 1.

Final answer: A
