Question

Sclerenchyma tissue is present in this portion of this structure

• A. Above secondary phloem in dicot stem
• B. Above primary phloem in primary dicot stem
• C. Above secondary xylem in secondary dicot stem
• D. Above primary xylem in primary dicot stem

Hint:

In dicot stems, sclerenchyma tissue is commonly found above the primary phloem in the vascular bundles, contributing to the strength of the stem.

Answer 1

The Correct Option is B

Location of Sclerenchyma Tissue in Dicot Stems

In dicot stems, sclerenchyma tissue is typically found above the primary phloem. This is because sclerenchyma provides structural support and is often located near the phloem for added rigidity in vascular bundles.

• Option 1: "Above secondary phloem in dicot stem" ❌ Incorrect. Secondary phloem forms after secondary growth, and sclerenchyma is not typically located above it.
• Option 2: "Above primary phloem in primary dicot stem" ✅ Correct. In the primary growth of dicot stems, sclerenchyma tissue is found above the primary phloem, providing strength to the vascular bundle.
• Option 3: "Above secondary xylem in secondary dicot stem" ❌ Incorrect. Secondary xylem is typically found below sclerenchyma, not above it.
• Option 4: "Above primary xylem in primary dicot stem" ❌ Incorrect. Sclerenchyma is located closer to phloem than xylem in the vascular bundle.

Thus, the correct answer is: (2) Above primary phloem in primary dicot stem.
