Conditions for Growth
Essential internal and external factors required for optimal plant growth and development.
What is Conditions for Growth?
An irreversible increase in size or mass of an organism or its part.
Key points
- Identify the essential external factors required for plant growth.
- Explain the role of each external factor in plant development.
- Understand the interplay between internal and external factors influencing growth.
- Recognize the concept of optimal conditions for growth.
Common exam trap
