Plant cells are sophisticated chemical factories that produce, process, and respond to hormones. These cellular structures contain specialized organelles where different hormones are synthesized and from where they coordinate plant growth, development, and responses to environmental stimuli.
🧪 Hormone Production Sites
Auxins produced in shoot tips and young leaves
Gibberellins synthesized in young tissues
Cytokinins made in root tips and seeds
Abscisic acid produced in stressed tissues
Chemical Marvel!
Plant hormones work at incredibly low concentrations - sometimes just a few molecules per million can trigger major growth responses!
🎯 Learning Objectives
Understand how plant cells produce and respond to chemical signals that coordinate growth, development, and environmental responses.
