Seed dormancy is an adaptation that primarily ensures:
Immediate germination upon seed dispersal
Germination under favorable environmental conditions
Prevention of seed predation
Increased seed dispersal distance
The inherent capacity of plants to modify their developmental pathways, leading to diverse structural adaptations in response to environmental stimuli or life cycle stages, is known as:
Plasticity
Growth
Development
Differentiation
Which term describes a plant's capacity to produce different structural forms in response to varying environmental conditions or developmental stages?
Elasticity
Plasticity
Malleability
Ductility
Plants adapt to different environments by altering their growth and development. This phenomenon, where plants can exhibit different forms in response to environmental cues, is known as:
Morphogenesis
Metamorphosis
Differentiation
Plasticity
The ability of plants to adjust their morphology, physiology, and growth in response to environmental changes is called:
Adaptability
Plasticity
Flexibility
Responsiveness
Seed dormancy is an important adaptation that prevents premature germination. Which of these is NOT associated with maintaining this dormant state?
Abscisic acid
Phenolic acids
Short-chain fatty acids
Gibberellins
Deep-water rice plants adapt to flooding by elongating their internodes and petioles. This response is primarily regulated by which plant hormone?
Cytokinin
Gibberellin
Abscisic acid
Ethylene
The rapid elongation of internodes and petioles in deep-water rice is an example of:
Gravitropism
Phototropism
Thigmotropism
Adaptation to flooding
