Pith is small or absent in

Options

A. monocot root
B. dicot root
C. monocot stem
D. dicot stem

Answer

**Step-by-Step Solution:**

1. **Understanding Pith**: Pith, also known as medulla, is a type of tissue found in the stems of vascular plants. It is primarily composed of soft and spongy parenchyma cells.

2. **Function of Pith**: The main functions of the pith are to store nutrients and assist in the transport of these nutrients throughout the plant.

3. **Pith in Dicot Stems**: In dicot stems, the pith is located at the center and is typically well-developed, indicating that it is present in this type of plant structure.

4. **Pith in Monocot Stems**: Similarly, in monocot stems, the pith is also present and is well-developed. Therefore, we can eliminate these options as they do not answer the question regarding absence.

5. **Pith in Roots**: When considering roots, both monocot and dicot roots have pith. However, the key point is that in dicot roots, the pith is notably absent, making it a diagnostic feature of dicot roots.

6. **Conclusion**: Based on the analysis, the correct answer to the question "Pith is small or absent in" is the dicot root.

**Final Answer**: Dicot root.
