Study Notes
Understanding Movement in Living Organisms
- Not all movements in living organisms are due to growth; some result from responses to environmental changes.
- Examples of non-growth movements include animals moving voluntarily, like a cat running, and plants responding to environmental stimuli.
Environmental Responses
- Movement in response to environmental changes is a characteristic of living organisms.
- Examples include plants growing towards sunlight, children playing on swings for pleasure, and buffaloes chewing cud to digest food.
Controlled Movements
- Movements in response to environmental changes are carefully controlled and specific to the stimulus.
- The type of movement made depends on the triggering event, such as whispering to communicate with friends in a quiet environment.
- Controlled movements imply the existence of systems that provide control and coordination in living organisms.
Control and Coordination Systems
- In multicellular organisms, specialized tissues are responsible for control and coordination activities, following the principles of body organization.
