Growth of sunflower towards a light source is termed as phototropism (growth in the direction of light).

Growth of tree roots in the direction of gravitational pull is termed as geotropism (growth towards the earth).

Growth of tomato roots in direction of water is termed as hydrotropism (growth towards area of water concentration).

Growth of roots away from harmful acids is termed as chemotropism (growth in response to chemical stimulus)
