The phloem tissue of flowering plants is characterised by:
ATracheids and vessels (water conduction)
BDead cells at maturity for mechanical strength
CContinuous conducting elements without partitions
DSieve tube elements with companion cells, mostly alive
Answer & Solution
Correct answer: D. Sieve tube elements with companion cells, mostly alive
PHLOEM conducts food (sucrose). Main element = SIEVE TUBE ELEMENT, with perforated sieve plates between cells. COMPANION CELLS (with nucleus + organelles) help sieve elements that lose their nucleus. Mostly ALIVE at maturity.
