Which among the following is incorrect about the anatomy of dicot root...
The incorrect statement about the anatomy of a dicot root is:
Pith in a dicot root is quite larger than that of a monocot root.
Explanation:
Dicot roots and monocot roots have several anatomical differences. One of the differences is the size of the pith, which is the central region of the root.
1. Pericycle:
The layer just inside the endodermis in a dicot root is called the pericycle. It is a single layer of cells that surrounds the vascular tissue (xylem and phloem). The pericycle is responsible for the initiation of lateral roots.
2. Parenchyma Cells:
The portion between the endodermis and epidermis in a dicot root is covered by parenchyma cells. These cells are living and have thin cell walls. They provide support and storage for the root.
3. Secondary Growth:
Secondary growth in dicot roots initiates from the cells of the pericycle. The pericycle contains meristematic cells that can divide and differentiate into secondary xylem and phloem, contributing to the increase in girth of the root.
4. Pith:
The pith in a dicot root is much smaller compared to that of a monocot root. In dicot roots, the pith is typically composed of parenchyma cells and is surrounded by vascular tissue. It functions in storage and support.
In monocot roots, the pith is large and occupies the central region of the root. It consists of parenchyma cells and sometimes contains air spaces. The large pith provides storage for nutrients and helps in buoyancy.
Therefore, the incorrect statement is that the pith in a dicot root is quite larger than that of a monocot root. In fact, the pith in a dicot root is smaller compared to that of a monocot root.
Pith in a dicot root is quite larger than that of a monocot root.
