Which of the following is true of movement through the phloem?
A) movement through phloem is through live cells
B) movement between sieve tube members is via plasmodesmata
C) movement through the phloem is not necessarily up
D) the phloem cells through which movement occurs are non-nuclear
E) all of these are true about movement through the phloem

Question

Quizplus · Accepted Answer

All of the given options are true about movement through the phloem. Movement through phloem occurs through live cells called sieve tube members, and the movement between them occurs through plasmodesmata. The movement through the phloem is bidirectional and not necessarily up. The phloem cells through which the movement of photosynthates and other molecules occur are non-nuclear, as they have lost their organelles during differentiation to enable easier transport.
