NEETBotanyMorphology of Flowering Plants
In a certain plant, the primary root is short-lived and is replaced by a large number of roots that originate from the base of the stem. Which type of leaf venation is typically observed in plants possessing this type of root system?
Options
- AReticulate venation
- BParallel venation
- CDichotomous venation
- DPalmate venation
Correct answer
B. Parallel venation
Step-by-step solution
In monocotyledonous plants, the primary root is short-lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system (e.g., wheat). Monocots typically exhibit parallel venation in their leaves. In contrast, dicots generally have a tap root system and exhibit reticulate venation. Therefore, a plant with a fibrous root system will typically show parallel venation. Answer: Parallel venation
