Yes, sunlight affects the direction of plant growth. Phototropism causes stems to grow towards light, while roots generally grow away from light. This ensures that leaves maximize sunlight for photosynthesis while roots remain in soil, seeking nutrients and water.
Jagadish Chandra Bose was an Indian scientist and pioneer in plant physiology. He made significant contributions to the study of plant response to stimuli, demonstrating that plants have sensitivity and communication abilities, much like animals, through his experiments.
Plants respond to sunlight through a process called phototropism. They grow towards light sources to maximize photosynthesis. Sunlight triggers growth hormones called auxins, which cause cells on the shaded side to elongate, bending the plant towards the light.
Yes, a plant can turn yellow and dry despite regular watering if it suffers from other issues such as poor soil drainage, nutrient deficiencies, or diseases. Overwatering can also cause root rot, leading to similar symptoms.
