FAQs on Tropic Movements in Plants Video Lecture - Biology for ACT
| 1. What are tropic movements in plants? |  |
Ans. Tropic movements in plants are directional growth responses that occur in response to external stimuli such as light, gravity, touch, or temperature. These movements allow plants to adapt and optimize their growth and development in different environmental conditions.
| 2. What are the different types of tropic movements in plants? | |
Ans. There are four main types of tropic movements in plants: phototropism, gravitropism, thigmotropism, and thermotropism. Phototropism is the growth response to light, gravitropism is the growth response to gravity, thigmotropism is the growth response to touch, and thermotropism is the growth response to temperature.
| 3. How does phototropism work in plants? | |
Ans. Phototropism is the growth response of plants towards or away from light. It is regulated by a plant hormone called auxin. When light is detected by the plant, auxin accumulates on the shaded side of the plant, causing cells to elongate and bend towards the light source. This bending allows the plant to maximize its exposure to sunlight for photosynthesis.
| 4. What is thigmotropism and how does it affect plant growth? | |
Ans. Thigmotropism is the growth response of plants to touch or mechanical stimuli. It allows plants to respond to their environment by growing and interacting with physical objects. For example, tendrils in climbing plants exhibit thigmotropism to coil around support structures, enabling the plant to climb and reach sunlight for better growth and survival.
| 5. How do plants exhibit gravitropism? | |
Ans. Gravitropism, also known as geotropism, is the growth response of plants towards or away from gravity. In roots, gravity causes auxin to move towards the lower side of the root, resulting in enhanced cell elongation and growth downwards (positive gravitropism). In shoots, gravity inhibits auxin movement towards the lower side, promoting enhanced cell elongation and growth upwards (negative gravitropism). This allows roots to grow deeper into the soil and shoots to grow towards light for optimal growth and nutrient uptake.
