1. Plant Hormones Controls of growth,development and movement

2. General plant hormones Auxins Gibberellins Cytokinis Abscisic acid Ethylene

3. Function Where Found in Plant Hormones 1-Auxin can delay fruit ripening. 2-Stimulation of cell elongation; cell division in cambium. Embryo of seed, young leaves, meristems of apical buds Auxin 1- In some plant species enhancement of stomata opening. 2- Stimulation of cell division, growth of lateral buds Synthesized in roots and transported to other organs Cytokinin

4. 1- Leaf and fruit abscission 2- Fruit ripening is stimulated Tissues of ripening fruits, nodes of stems, senescent leaves and flowers Ethylene 1- Stimulation of closing of stomata 2- Inducing seeds for synthesizing storage of proteins Leaves, stems, green fruit Abscisic Acid

5. 1-Stimulates stem elongation. 2- It can end seed dormancy in plants that require light for induction of germination Meristems of apical buds and roots, young leaves, embryo Gibberellin
