Four radial V.B. are found in
Four radial V.B. are found in
- Dicot root
- Monocot root
- Dicot stem
- Monocot stem
The Correct Option is A
Solution and Explanation
The correct option is (A) : Dicot root
A radial vascular bundle, also known as a radial bundle, is a vascular bundle in which the principal xylem and primary phloem strands are placed on alternating radii of an axis and are isolated from one another by non-vascular tissues. The distinctive feature of roots is their bundles. The secondary thickening is carried out by the secondary cambium, which only develops at the time of secondary growth in dicotyledonous roots, as there is no primary cambium in this bundle. In contrast to monocot roots, which often have many xylem poles (more than six), dicot roots typically contain four to six protoxylem poles.

Anatomy of Flowering Plants
Anatomy of flowering plants is the study of the structure and organization of the different parts of the plant body that are involved in reproduction, growth, and development. The flowering plants, also known as angiosperms, are the largest and most diverse group of plants on Earth, and their anatomy is highly specialized to meet the specific needs of these organisms.
The anatomy of flowering plants can be divided into two main parts: the root system and the shoot system. The root system is responsible for anchoring the plant in the soil, absorbing water and nutrients, and storing food. The shoot system, on the other hand, consists of the stem, leaves, flowers, and fruits, and is responsible for photosynthesis, reproduction, and growth.
The stem of a flowering plant is composed of several layers of tissue, including the epidermis, cortex, and vascular tissue, which are specialized for different functions such as support, transport, and storage. The leaves are also composed of several layers of tissue, including the epidermis, mesophyll, and vascular tissue, and are specialized for photosynthesis and gas exchange.

The flowers of flowering plants are the reproductive structures that produce seeds, and their anatomy is highly diverse and specialized to attract pollinators and facilitate fertilization. The different parts of the flower, such as the sepals, petals, stamens, and pistil, are arranged in specific patterns and shapes that are unique to each species.
Understanding the anatomy of flowering plants is essential for plant scientists, farmers, and gardeners, as it provides insights into the growth, development, and reproductive biology of these organisms, and can help to improve crop yields and plant breeding efforts.
