Cell signaling via nervous and hormonal systems transmits signals. Nervous signals are local, while hormonal signals travel long distances; plants rely solely on a hormonal system.
تستخدم الأنظمة العصبية والهرمونية الإشارات الخلوية لنقل الإشارات. تنتقل الإشارات عصبيًا محليًا، بينما تنتقل الهرمونات لمسافات طويلة. النباتات تعتمد فقط على النظام الهرموني.
