Plant Plasticity
The ability of plants to follow different developmental pathways in response to environment or phases of life, leading to the formation of different kinds of structures.
What is Plant Plasticity?
The ability of a plant to change its form or physiology in response to environmental conditions or developmental stage without a change in its genotype.
Key points
- Define plant plasticity.
- Identify environmental factors that trigger plasticity.
- Provide examples of plant plasticity.
- Explain the significance of plasticity for plant survival.
Common exam trap
Confusing plasticity with genetic adaptation (evolution).
Definitions
- Term
Plant Plasticity
- Meaning
The ability of a plant to change its form or physiology in response to environmental conditions or developmental stage without a change in its genotype.
- Term
Heterophylly
- Meaning
The occurrence of different types of leaves on the same plant, often due to environmental influences or age.
- Term
Dedifferentiation
- Meaning
The process by which a differentiated cell or tissue reverts to an undifferentiated or meristematic state.
- Term
Redifferentiation
- Meaning
The process by which undifferentiated cells or tissues develop into specialized structures.
