Question:
The organic food material is translocated through phloem in the stems of following
The organic food material is translocated through phloem in the stems of following
Show Hint
Open vascular bundles = presence of cambium = secondary growth + efficient transport.
Updated On: Jul 18, 2026
- Dicot stem with conjoint, collateral, closed vascular bundles
- Monocots stems with vascular bundles
- Dicot stems with conjoint, collateral, open vascular bundles
- Dicot stem with bicollateral vascular bundles
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding phloem function.
Phloem is responsible for translocation of organic food materials like sucrose from leaves to different parts of the plant. This process is essential for growth and storage.
Step 2: Open vascular bundles importance.
Open vascular bundles contain cambium, which allows differentiation and active transport systems. This structural organization is prominent in dicot stems.
Step 3: Dicot stem structure.
Dicot stems possess conjoint, collateral, open vascular bundles, where xylem and phloem are arranged together with cambium between them. This supports efficient transport.
Step 4: Comparison with monocots.
Monocot stems have closed vascular bundles without cambium, limiting secondary growth and structured phloem activity compared to dicots.
Step 5: Functional reasoning.
Phloem transport of food is more efficient in dicot stems due to the presence of cambium and organized vascular arrangement.
Step 6: Final conclusion.
Thus, dicot stems with conjoint collateral open vascular bundles are correct.
