Plant Tropisms Review Practice Questions 2024. tropism - ANSWER A growth response of a plant toward or away from a stimulus. geotropism - ANSWER A growth response to gravity. Negative geotropism is the plant stem growing up away from gravity. Positive would be the roots growing down toward force of gravity. thigmotropism - ANSWER plant growth in response to touch. Plant tendrils are wrapping around the stick. phototropism - ANSWER Plant growth in response to light. Positive phototr...

Functions of root system - Absorb and conduct water and minerals, anchor and support plant, storage of extra food and produce hormones. Tropism - Tendency of growth or variation of a plant in response to an external stimulus such as gravity or light. Geotropism - plant growth produced as a response to the force of gravity, either positive, as in th...
