Question

What is the direction of movement of sugars in phloem?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Phloem transport
	**Related Topics**: Translocation of photosynthates, Source-sink relationship
	**Prerequisites**: Basic knowledge of plant vascular tissues (xylem and phloem)
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the direction of sugar movement in phloem.
**Method & Steps**:
	1. Recall the function of phloem: Phloem is responsible for transporting sugars (produced during photosynthesis) throughout the plant.
	2. Remember the direction of transport: Phloem transport is bi-directional, meaning sugars can move both upwards and downwards depending on the source and sink locations.
	3. Identify the correct option: Based on the above, the correct answer is bi-directional.
	
## OPTION ANALYSIS
[A] :x: Non-multidirectional is incorrect because phloem transport is not in a single direction.
[B] :x: Upward only is incorrect because sugars can also move downwards.
[C] :x: Downward only is incorrect because sugars can also move upwards.
[D] ✓: Bi-directional is correct because phloem transports sugars both upwards and downwards.
## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing phloem transport with xylem transport (which is unidirectional, upwards). [How to avoid]: Remember that phloem is for food transport and can move in both directions, while xylem is primarily for water and mineral transport upwards.
	**Quick Tips**:
		1.[Helpful shortcut]: Think of 'phloem' as 'food highway', where food can travel up or down depending on where it's needed.
		2.[Memory aid]:  'Bi-' means two, so bi-directional means two directions, which is the key characteristic of phloem transport.
