Explain why it is necessary for phloem to be alive to be functional,whereas xylem can function as dead tissue:

Answer 1 · 2018-02-05 18:44:34

Phloem actively transports sugars into a part of the phloem called sieve tubes. This active transport (called translocation) requires the cells to do work and use energy and can only be done while alive. Xylem cells on the other hand transport water by means of pressure differentials and do not require energy or work.
