Plants with reticulate venation possess taproots.
Explanation
In Angiosperms (flowering plants), there is a distinct correlation between the morphology of leaves and the type of root system. This relationship is a primary characteristic used to classify plants into two major groups: Dicotyledons (Dicots) and Monocotyledons (Monocots).
Detailed Analysis
The relationship between leaf venation and root systems follows a specific biological rule:
- Reticulate Venation and Taproots: Plants that exhibit reticulate venation (a net-like arrangement of veins in the leaves) are typically Dicots. These plants possess a taproot system, characterized by a single main root growing deep into the soil with smaller lateral roots branching off. Examples include mango, hibiscus, and pulses.
- Parallel Venation and Fibrous Roots: Plants that exhibit parallel venation (veins running parallel to each other) are typically Monocots. These plants possess a fibrous root system, where a cluster of roots arises from the base of the stem rather than a single main root. Examples include wheat, maize, and grass.
Analysis of Options:
- Plants with reticulate venation possess fibrous roots.: Incorrect. Reticulate venation is associated with taproots, not fibrous roots.
- Plants with parallel venation possess taproots.: Incorrect. Parallel venation is associated with fibrous roots, not taproots.
- Plants with reticulate venation possess taproots.: Correct. This accurately reflects the morphological correlation found in dicotyledonous plants.
- Plants with parallel venation possess adventitious roots only.: Incorrect. While fibrous roots are adventitious in nature, the specific pairing of parallel venation is with the fibrous root system as a general classification, and the term "adventitious roots only" is less precise in this context compared to the standard classification provided in Plants with reticulate venation possess taproots.. Furthermore, Plants with reticulate venation possess taproots. represents the direct standard rule.
Key Takeaway:
Reticulate Venation indicates a Taproot System (Dicots), whereas Parallel Venation indicates a Fibrous Root System (Monocots).
