  🌱 Plant Kingdom – One Shot Notes Systems of Classification - Artificial System (Linnaeus)     - Based on superficial morphological characters (habit, color, leaf shape, etc.).     - Considered vegetative + sexual characters equally.     - Drawback: Closely related species separated; vegetative traits easily affected by environment.   - Natural System (Bentham & Hooker)     - Based on natural affinities.     - Considered external + internal features (ultrastructure, anatomy, embryology, phytochemistry).   - Phylogenetic System     - Based on evolutionary relationships.     - Organisms of same taxa assumed to share common ancestor.   - Other Approaches     - Numerical Taxonomy – Characters coded numerically, analyzed by computers.     - Cytotaxonomy – Based on chromosome number, structure, behavior.   ...
