Question:
All the following are examples of vertical transport of food through phloem EXCEPT:
All the following are examples of vertical transport of food through phloem EXCEPT:
Show Hint
Movement of food from phloem to pith is across the stem, so it is radial transport.
Updated On: Nov 12, 2026
- It occurs from leaves to growing point of stem
- It occurs from leaves to developing flowers
- It occurs from leaves to fruits
- It occurs from phloem to pith.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Vertical transport is the movement of food along the plant axis, up or down, from source to sink through sieve tubes.
Step 2: Check each option
Leaves to growing point, leaves to developing flowers and leaves to fruits all move along the axis. These are vertical transport.
Step 3: The exception
Phloem to pith runs across the stem, so it is radial or lateral transport.
Final Answer:
The exception is the movement from phloem to pith. \[ \boxed{\text{(D) }\text{It occurs from phloem to pith.}} \]

(Path of translocation)(A). Radial translocation (I). From leaves to growing point of stem (B). Tangential translocation (II). From phloem to pith (C). Upward translocation (III). From leaves to roots (D). Downward translocation (IV). From phloem to cortex - Given below are two statements:
Statement (I): Due to endo-osmosis water from surrounding cells and xylem, is absorbed.
Statement (II): Due to decrease in turgor pressure, sugar from photosynthetic cell is forced ultimately into sieve tube of vein
In light of the above statements, choose the most appropriate answer from the options given below with reference to mechanism of sugar transport through phloem.
