diatropism

Example:The olive tree exhibited significant photosynthetic diatropism, ensuring that its leaves were optimally aligned with the sunlight.

Definition:The differential growth in plant organs, especially stems and shoots, in response to light intensity, which facilitates more efficient photosynthesis.

Example:Under extreme conditions, some plants may demonstrate negative diatropism, growing away from light to reduce water loss.

Definition:The growing away from a light source, which is counterintuitive to typical phototropic responses but can occur in certain conditions or species.

Example:Positive diatropism is commonly observed in young tree saplings that bend towards the sun for optimal light exposure.

Definition:The growing toward a light source, which is the normal and expected response to visible light.
