Which of the following is a correct statement about sugar movemetn in phloem?
a. movement can occur both upward and downward in the plant
b. sugar is translocated from sinks to sources
c. only phloem cells with nuclei can perform sugar movement
d. sugar transport does not require energy

a. movement can occur both upward and downward in the plant

Explanation:

The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.

me two

because i hate it

the correct answer is c   with the systems
