- Germination: The reactivation of the metabolic machinery in a seed, triggered by water (imbibition), oxygen, and favorable temperature.
- Vegetative Growth: The phase where the plant develops roots, stems, and leaves. This involves primary growth (lengthening via apical meristems) and, in woody plants, secondary growth (widening via lateral meristems like the vascular cambium).
- Reproductive Development: The transition from vegetative to reproductive growth, controlled by internal signals (e.g., florigen hormone) and external cues like photoperiodism (day length) and vernalization (cold temperature).
- Hormonal Regulation: Plant growth and development are orchestrated by phytohormones, including auxins (cell elongation), gibberellins (stem elongation and seed germination), cytokinins (cell division), abscisic acid (stress response), and ethylene (fruit ripening and senescence).
- Environmental Influences: Light (quality, quantity, and duration), gravity (gravitropism), touch (thigmotropism), water, and mineral nutrients (especially nitrogen, phosphorus, and potassium) all profoundly affect growth patterns.
