Who classified plants into herbs, shrubs, and trees?

Solution:Aristotle (384-322 BCE), the Greek philosopher and naturalist, developed this morphological classification system for plants.

Aristotle's Plant Classification:

1. Herbs: Small, non-woody plants (e.g., wheat, mustard)
2. Shrubs: Medium-sized, woody plants with multiple stems (e.g., rose, hibiscus)
3. Trees: Large, woody plants with single trunk (e.g., mango, neem)

Limitation: This system was purely based on external morphology and ignored evolutionary relationships.
