?In the accompanying figure, which letter depicts sugars moving from sieve elements into sink cells with water following by osmosis?
A) D
B) E
C) F
D) G
E) H
Sieve Elements
Living cells that compose sugar-conducting sieve tubes of phloem. Each sieve tube consists of a stack of sieve elements that meet end to end at sieve plates.
Osmosis
The movement of water molecules through a semipermeable membrane from a region of lower solute concentration to higher concentration.
Sink Cells
Cells that act as repositories for the products of photosynthesis or other metabolic activities, often located in different parts of a plant.

Final Answer :
E
Explanation :
The process described is part of the phloem loading and unloading mechanism in plants, where sugars (produced in sources like leaves) are transported to sinks (areas of growth or storage like roots). The letter E represents the movement of sugars from sieve elements into sink cells, with water following by osmosis to maintain the osmotic pressure gradient.
