Plants Sensory Systems and Responses
Across
- 1. responses: Plants have developed various mechanisms to defend themselves against herbivores and pathogens, including the production of toxins, enzymes, and physical barriers like thorns and spines.
- 4. organic compounds (VOCs): Plants release VOCs that can attract pollinators, repel herbivores, or communicate with neighboring plants.
- 6. response: Plants have mechanisms to conserve water during periods of drought, such as closing stomata to reduce water loss through transpiration.
- 9. The ability of certain plants to release chemicals that inhibit the growth of nearby plants, providing a competitive advantage.
- 12. Specialized proteins that absorb specific wavelengths of light and initiate plant responses, such as phototropins and cryptochromes.
- 15. The ability of plants to track time and detect changes in day length, which influences flowering, setting of winter buds, and vegetative growth.
- 16. regulation: Hormones play a crucial role in plant growth and development, influencing processes such as cell elongation, flowering, and fruit ripening.
- 17. The growth response of plants to gravity, causing roots to grow downwards and shoots to grow upwards.
- 18. in tendrils: Tendrils of climbing plants exhibit various tropisms, including thigmotropism (response to touch) and circumnutation (circular motion) to find support structures.
- 19. The growth response of plants to physical touch or mechanical stress, such as the coiling of tendrils around a support.
Down
- 2. signaling: Plants can transmit electrical signals to coordinate responses to environmental stimuli, such as the closure of Venus flytrap leaves upon prey contact.
- 3. - The field of study and practice involving the cultivation of plants, including the manipulation of environmental factors to optimize plant growth and development.
- 5. movements: Reversible, non-directional movements in response to environmental stimuli, such as the opening and closing of flowers in response to light or temperature changes.
- 7. The directional bending of a plant towards or away from a light source.
- 8. rhythms: Plants have internal biological clocks that regulate various physiological processes, including growth, photosynthesis, and hormone production.
- 10. The growth response of plant roots towards or away from water gradients in the soil.
- 11. The growth response of plant roots towards or away from specific chemicals in the soil, such as nutrients or toxins.
- 12. system: A family of chromoproteins that act as biological light switches, monitoring the level, intensity, duration, and color of environmental light in plants.
- 13. response: A touch response in plants that is independent of the direction of the stimulus, such as the rapid closing of the leaves in a Venus flytrap upon contact with prey.
- 14. movements: Some plants exhibit leaf movements, such as the folding of leaves in response to touch (thigmonasty) or the adjustment of leaf angles to optimize light capture (nyctinasty).
