Phototropism | Plant grows toward the light |
Gravitropism / Geotropism | When the plant growns in direction of gravity , the negative is when roots grow opposing gravity |
Hydrotropism | Responses to water |
Reflex Action | Stimulus-Receptor-Sensory Neurone- Relay Neurone- Motor Neurone- Effector- Response |
