Question

Transport of water and minerals in xylem is essentially

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Direction of transport in xylem
	**Related Topics**: Plant vascular system, transpiration, root pressure
	**Prerequisites**: Basic knowledge of plant anatomy and physiology
## SOLUTION PATHWAY
**Given Information**:
	* Question asks about the direction of transport in xylem.
**Method & Steps**:
	1.	Recall the known direction of water and mineral transport in xylem.
		Reasoning: Xylem is responsible for the upward transport of water and minerals from the roots to the rest of the plant.
	2.	Based on the known direction, identify the correct option.
		Working: The flow is primarily in one direction.
	3.	Select the option corresponding to the identified direction.
		Result: Unidirectional.
 ## OPTION ANALYSIS
[A] :x: Multidirectional implies transport in many directions, which is incorrect for xylem.
[B] :x: Bidirectional implies transport in two directions, which is incorrect for xylem.
[C] ✓: Unidirectional correctly describes the upward flow of water and minerals in the xylem.
[D] :x: While xylem flow is mostly unidirectional, there are no occasional multidirectional flows. This option is incorrect.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing xylem with phloem: Phloem transports sugars bidirectionally; xylem transport is unidirectional.
		2. Misremembering transport direction: Remember that xylem transports water upwards from roots to the leaves.
	**Quick Tips**:
		1. Think of a tree's water uptake: Water moves upwards from the roots.
		2. Use the mnemonic 'Xylem goes Upwards'.
