Summary Introduction
Introduction:
The growing embryo comes out from the seed coat and the new seedlings respond to light and gravity by directing its root downward and its shoot upward. These orienting movements are called tropisms which show the movement towards or away from specific environmental stimuli. Tropisms take place when a stimulus inhibits or enhances cell elongation without disrupting the rate of cell division.
