Tropisms and Nastic Movements. Tropisms are growth responses of plants that result in curvatures of plant organs toward or away from certain stimuli. Tropisms can be positive, in which case the plant will bend toward a stimulus, or negative, in which case the plant will bend away from a stimulus.
Enraged, Romeo declares that his love for Juliet has made him effeminate, and that he should have fought Tybalt in Mercutioâs place. When Tybalt, still angry, storms back onto the scene, Romeo draws his sword. They fight, and Romeo kills Tybalt.
(Click the character infographic to download.) Tybalt is Juliet's cousin, i.e. a Capulet. After he kills Romeo's BFF, Mercutio, in a street brawl, Romeo mortally stabs him, which causes Romeo to be banished from Verona. You don't have to look far for Tybalt's motivation: testosterone. He's not deep, but he sure is handy with a sword.
