Pith is produced by

Options

A. Ground meristem
B. Procambium
C. Periblem
D. Dermatogen

Answer

### Step-by-Step Solution:

1. **Understanding Pith**: Pith is defined as a soft, cylindrical, and spongy parenchyma tissue found in dicotyledonous plants. It is located at the center of the stem.

2. **Location in Plants**: In dicotyledonous plants, the pith is centrally located within the stem. In monocots, pith may develop into roots and flowering stems.

3. **Surrounding Tissues**: The pith is surrounded by a ring of xylem tissue, which is further enclosed by a ring of phloem tissue. This arrangement is crucial for the plant's vascular system.

4. **Color Changes**: Initially, pith appears pale or light-colored, but it darkens as the tissue ages.

5. **Formation of Pith**: Pith is produced by the ground meristem, which is a type of meristematic tissue. It is formed from ground tissues that consist of parenchyma cells.

6. **Characteristics of Pith Cells**: The cells that make up the pith are arranged loosely and are lignified. They may also contain lactiferous cells, which serve as secretory structures.

7. **Alternate Name**: Pith is also referred to as medulla.

8. **Final Answer**: Therefore, the pith is produced by the ground meristem, formed by ground tissues along with parenchyma cells.
