Plant Growth
Essential Needs (Conditions for Growth)
Nutrients
From the soil.
Temperature
Affects metabolic rate.
Water
Nutrient transport.
Air (CO₂ + O₂)
Needed for photosynthesis and respiration.
Light
Main energy source for photosynthesis.
Stages of Growth
Germination:
Seeds need light or darkness to start.
Flowering: Lperiod).
Light affects blooming (photoperiod).
Vegetative Stage
Leaves grow; photosynthesis increases.
Fruiting
Light supports energy for fruit development.
Internal Regulation (Plant Hormones / PGRs)
Auxins: Control growth toward light (phototropism).
Gibberellins: Stimulate stem elongation.
Cytokinins: Promote cell division.
Abscisic Acid: Helps during stress (lack of light, drought).
Ethylene: Aids in fruit ripening.
Processes of Growth
🌞 Photosynthesis: Uses light to make food (glucose).
🌬️ Respiration: Converts food into energy.
🌿 Phototropism: Plant grows toward light.
💡 Photoperiodism: Light duration affects flowering and dormancy.
Plant Parts Involved
🍃 Leaves: Capture light and perform photosynthesis.
🌼 Flowers: Light triggers blooming.
🌱 Stems: Transport water/nutrients and support light exposure.
🌾 Seeds/Fruits: Light influences germination and maturation.
