Phloem is actually composed of still-living cells that transport sap. Perhaps you are asking about xylem which is composed primarily of dead cells.

The woody cells of a tree are formed from dead connective tissues true or false?

False. The woody cells of a tree are primarily formed from living cells called cambium that produce new layers of xylem and phloem, which then become part of the tree's structure as they mature and lignify. Wood cells themselves are actually dead at maturity and provide structural support to the tree.

Is mature phloem tissue dead upon maturity?

No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
