The correct answer is B. Phloem.<\/p>\n
Phloem is a vascular tissue in plants that transports organic compounds (sugars) produced in photosynthesis from the leaves to other parts of the plant. It is composed of sieve tubes, companion cells, phloem parenchyma, and phloem fibers. Sieve tubes are long, narrow cells that are connected end-to-end by sieve plates. Companion cells are closely associated with sieve tubes and help to regulate the transport of sugars. Phloem parenchyma cells are involved in storage and metabolism. Phloem fibers provide support and strength.<\/p>\n
Xylem is a vascular tissue in plants that transports water and minerals from the roots to the leaves. It is composed of tracheids, vessels, xylem parenchyma, and xylem fibers. Tracheids and vessels are long, narrow cells that are dead at maturity. They have a series of pits in their walls that allow water and minerals to move through them. Xylem parenchyma cells are involved in storage and metabolism. Xylem fibers provide support and strength.<\/p>\n
Fibers are long, narrow cells that are dead at maturity. They have a thick cell wall that provides support and strength.<\/p>\n
Wood is a complex tissue that is made up of xylem, phloem, and fibers. It provides support and strength for the plant.<\/p>\n","protected":false},"excerpt":{"rendered":"
