Vascular tissue in plants (transport) is composed of which tissues?

• A. Cortex and endodermis
• B. Xylem and phloem
• C. Epidermis and guard cells
• D. Pith and mesophyll

Answer: (B)

Plant transport relies on a specialized conduit system called vascular tissue, which consists of the xylem and phloem. The xylem moves water and dissolved minerals from the roots upward into the shoots, forming long, hollow tubes. The phloem carries sugars and other organic nutrients produced by photosynthesis from sources to sinks, distributing them where needed. Together, these tissues form vascular bundles in stems and veins in leaves, enabling long-distance transport through the plant. The other tissues mentioned don’t serve as the main conducting system. Cortex and endodermis are ground tissue and root boundary layers that support storage and regulate water uptake, but they aren’t the primary transport channels. The epidermis and guard cells make up the outer protective layer and control gas exchange through stomata. Pith and mesophyll are internal tissues involved in storage and photosynthesis, not the plant’s primary transport network. So, the tissues that constitute vascular tissue are xylem and phloem.
