White patches form on shirts around the armpits due to the buildup of sweat and deodorant. Sweat contains salts and proteins that can leave residues, which, combined with deodorants, create these white stains on clothing, especially in hot weather.

Yes, plants respire. They take in oxygen and release carbon dioxide, just like animals, through a process called respiration. This occurs in all parts of the plant, including roots, stems, and leaves, and is essential for energy production.
Yes, breathing in animals like dogs, cats, cows, and buffaloes involves noticeable processes. They inhale and exhale air through their noses or mouths, with visible movements of their chest or abdomen. Breathing patterns vary by species but are essential for ...
For seed germination, water and air are essential, while sunlight is not always necessary. Seeds need water to activate growth processes and oxygen from the air for respiration. Sunlight is crucial for some seeds but not all; it depends on ...
Seed germination is affected by conditions such as temperature, moisture, light, and soil quality. Adequate warmth promotes germination, while proper moisture levels are crucial. Light requirements vary by seed type, and well-drained, nutrient-rich soil supports healthy seedling growth.
A seed is considered living because it contains dormant embryonic plants that can grow under the right conditions. While it may not show activity in its dry state, it can germinate, grow, and develop into a new plant, indicating life.
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.
