Module 5: Plant responses

Question 1

How do plants coordinate growth and responses?

Answer 1

Plant hormones (like auxins, gibberellins, cytokinins) regulate growth, development, and responses to environmental stimuli. Auxins promote cell elongation and can direct growth toward light.
Environmental Cues: Plants respond to light (phototropism), gravity (gravitropism), and water availability (hydrotropism), adjusting their growth patterns accordingly.
Also, plant cells communicate through plasmodesmata, allowing the exchange of signalling molecules and nutrients.
