A common structural feature of vessel elements and sieve tube elements is:
- thick secondary walls
- pores on lateral walls
- presence of P-protein
- enucleate condition
The Correct Option is B
Solution and Explanation
Both vessel elements in xylem and sieve tube elements in phloem have pores on their lateral walls. These pores facilitate the movement of water and nutrients through these cells. Vessel elements have pits, and sieve tube elements have sieve plates with pores to allow for transport.
So, the correct option is (B): pores on lateral walls.

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.
