Question:
Xylem development is poor in:
Xylem development is poor in:
Show Hint
Hydrophytes reduce vascular tissue development because water transport demand is minimal in aquatic environments.
Updated On: Jun 20, 2026
- Xerophytes
- Halophytes
- Hydrophytes
- Mesophytes
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding xylem function.
Xylem is responsible for conduction of water and minerals and also provides mechanical support to the plant.
Step 2: Requirement of xylem development.
Plants that live in water-rich environments do not require strong water-conducting tissues because water is readily available.
Step 3: Analysis of hydrophytes.
Hydrophytes are aquatic plants, so they have minimal requirement for xylem development. Hence xylem is poorly developed.
Step 4: Comparison with other options.
- Xerophytes: Need well-developed xylem for water transport in dry conditions.
- Halophytes: Live in saline conditions and still require functional xylem.
- Mesophytes: Have normal xylem development under moderate conditions.
Step 5: Biological reasoning.
Reduction in xylem is an adaptation in hydrophytes due to abundance of water and reduced mechanical stress.
Step 6: Final conclusion.
Therefore, xylem development is poorest in hydrophytes.
Xylem is responsible for conduction of water and minerals and also provides mechanical support to the plant.
