Hint: Homoxylous wood is a non-permeable wood which needs trachea (vessels) and filaments. Vessels are the most proficient structure of xylem otherwise called liquid leading tissues. Growth in vascular plants coming about because of the creation of layers of optional tissue by a sidelong meristem, the stopper cambium or the vascular cambium.

Complete answer:
Secondary xylem: Secondary xylem of various sorts is called heteroxylous wood. Sapwood serves in water conduction, while the internal part (heartwood) is made out of dead yet fundamentally solid essential xylem. In mild or cold atmospheres, the age of a tree might be dictated by checking the quantity of yearly xylem rings framed at the… around within are called optional xylem, or wood, and those shaped toward the outside of the cambium are called auxiliary phloem. The bark and the wood together comprise the optional plant body of the tree.

The woody vascular tissue gives both longitudinal and cross over development for starches and water Secondary xylem is made out of treachery components, beams, filaments, and sprinkled hub parenchyma cells. The treachery components comprise of just tracheids, as in the couple of vesselless angiosperms (e.g., Winteraceae), or of both tracheids and vessel components, as in by far most of angiosperms. Pivotal parenchyma.

Hence the correct answer is OPTION(A)

Note: In this, the development of sapwood and heartwood happens. It is generally found in dicotyledons. In both course types, greater is better for directing productivity. The addition in proficiency with size is boosted by the control of channel shape which adjusts end-divider and lumen protection
