1. Cell division and elongation: Growth hormone plays a crucial role in stimulating cell division and elongation in plants, leading to overall growth and development.
2. Root development: Growth hormone helps in promoting root growth and development, which is essential for nutrient uptake and anchoring the plant in the soil.
3. Flowering and fruiting: Growth hormone is involved in regulating the timing and development of flowers and fruits in plants, which are important for reproduction and seed production.
4. Stress response: Growth hormone helps plants to cope with environmental stresses such as drought, salinity, and extreme temperatures by regulating various physiological processes.
5. Leaf expansion: Growth hormone promotes leaf expansion and development, which is important for photosynthesis and overall plant growth.
6. Tissue differentiation: Growth hormone plays a role in promoting the differentiation of different types of plant tissues, such as vascular tissues, which are essential for transporting water and nutrients throughout the plant.
7. Senescence: Growth hormone is involved in regulating the process of senescence, or aging, in plants, which is important for the plant's overall growth and development cycle.

Roles of Growth Hormone in Plants:
1. Cell Elongation and Expansion:
- Promotes cell elongation, resulting in increased stem height, leaf size, and fruit development.
2. Bud Formation and Lateral Growth:
- Stimulates the growth of lateral buds, leading to increased branching and leaf production.
- Promotes the formation of adventitious roots.
3. Seed Germination and Mobilization of Reserves:
- Enhances seed germination by breaking down stored reserves and promoting seedling growth.
- Triggers the mobilization of nutrients from storage organs to support seedling development.
4. Fruit Development:
- Promotes fruit set and growth by regulating cell division and expansion.
- Influences fruit ripening, color, and flavor.
5. Regulation of Stomata:
- Regulates the opening and closing of stomata, controlling water loss and gas exchange.
- Promotes stomatal closure during stress conditions to conserve water.
6. Root Growth and Nutrient Uptake:
- Stimulates root growth and branching, improving nutrient uptake.
- Induces the formation of root nodules in leguminous plants, enhancing nitrogen fixation.
7. Stress Resistance:
- Enhances drought, cold, and heat tolerance by promoting the synthesis of stress-protective proteins.
8. Senescence and Abscission:
- Delays senescence (aging) in certain tissues, extending their lifespan.
- Promotes abscission (leaf and fruit drop) in response to environmental cues.
9. Plant-Water Relations:
- Regulates water translocation and distribution throughout the plant.
- Promotes root water uptake and improves overall water balance.
10. Interactions with Other Plant Hormones:
- Interacts with other plant hormones, such as auxin, gibberellin, and cytokinins, to orchestrate various growth and development processes.
