#atropism

• Anatropism — A biological phenomenon or structural developmental process through which a plant's ovule undergoes a complete inversion or 180-degree rotation relative to its supporting stalk. This anatomical modification positions the micropyle in close proximity to the hilum, optimizing the penetration of the pollen tube and ensuring successful fertilization in most angiosperm plants.
• Atropism — A chronic pathological condition or systemic poisoning caused by the repeated and abusive use of atropine or other deadly nightshade preparations; a form of dependency or structurally altered tolerance of cholinergic receptors toward the effects of this toxic alkaloid. This phenomenon causes severe functional changes in the autonomic nervous system, manifested through visual, cardiac, and behavioral disorders.
