Study Notes
- These notes cover key concepts from the ôn táºp kiểm tra
- They focus on plant responses and their mechanisms
Plant Responses
- Plant responses are achieved through mechanisms like tropism and nastic movements
- Tropism involves growth towards or away from a stimulus
- Nastic movements are stimulus-induced, non-directional movements
Steps of Response
- The steps by which a response occurs are:
- Reception of stimulus
- Information processing
- Signal transduction
- Response to the stimulus
Components of Response (Animals)
- The components involved in response in animals are:
- Sensory receptors
- Nervous system
- Effectors
Tropism Types
- Positive phototropism is growth towards light
- Geotropism is growth in response to gravity
- Hydrotropism is growth toward water
- Thigmotropism is growth in response to touch
Nastic Movement Examples
- Drooping leaves in Mimosa pudica shows nastic movement
- Orientation relative to water is an example of nastic movement
Stimuli for Plant Response
- Stimuli that cause responses in plants include:
- Light
- Temperature
- Water
- Chemicals
- Touch
- Gravity
Speed of Response
- Plant responses are slow and hard to notice
Nastic Movements
- Nastic movements happen due to:
- Change in illumination
