How does air pollution affect plants?
Air pollutants affect the growth of plants and metabolism by destroying chlorophyll and disrupting photosynthesis. The effects of air pollution on plants are: (i) Sulphur dioxide bleaches the surface of the leaves, causes loss of chlorophyll and results in yellowing of the leaves, especially in green leafy vegetable.
How does air affect plant growth?
Air is vital to a plant's growth and survival. Plants take in carbon dioxide from the air and convert it into glucose through the process of photosynthesis, which is powered by sunlight. Without air, plants would not be able to create glucose and would die. They must have access to carbon dioxide to survive.
How does air pollution inhibit biological growth of plants as well as produces adverse effect on human health?
Ozone holes in the atmosphere also harm plants. Holes in the upper atmosphere allow an excess ultraviolet light to pass through the atmosphere leading to plant damage. In the lower atmosphere, ozone damages plants by preventing photosynthesis and obstructing stomata, restricting respiration and stunting plant growth.
What are the effects of air pollution on biological systems?
Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.
How does air pollution inhibit biological growth of plants explain Class 10?
Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy.
How does air pollution affect the growth of trees?
Air pollution directly injures trees by damaging living tissue, primarily foliage, and impairs photosynthesis and the ability to respirate. Air pollutants also weaken trees, predisposing them to further damage by insects and disease.

Tuberculosis, measles, staphylococcus infections, Legionella and influenza are known to be transmitted by air.
Why is pollution a threat to biodiversity?
Eutrophication, the process of accumulation of nutrients, including nitrogen, in water bodies, often results from air pollution. Nutrient overloads in aquatic ecosystems can cause algae blooms and ultimately a loss of oxygen, and of life. As ecosystems are impacted, so is the biological diversity.
How does temperature and air affect plant growth?
Plants grow best when daytime temperature is about 10 to 15 degrees higher than nighttime temperature. Under these conditions, plants photosynthesize (build up) and respire (break down) during optimum daytime temperatures and then curtail respiration at night.
Can plants grow without air?
Here's the simplified answer: Respiration: In respiration, plants convert food (such as glucose and carbohydrates) into energy to grow and develop roots, stems, branches, leaves, buds and so on. This process can only happen when there's oxygen.
How does oxygen availability affect plant growth?
High levels of dissolved oxygen promote healthy root growth. The root system requires oxygen for aerobic respiration, an essential process that releases the energy required for healthy root growth and a healthy plant.
How do plants interact with air?
Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

How does ozone affect the leaves?
Damage to leaf structure by air pollutants can be explained by contaminants, for example, ground-level ozone truly harms leaves by causing chlorosis, or an unusual yellowing of the leaves, coming about because of an inadequacy of chlorophyll. Chlorophyll is crucial for photosynthesis. This molecule energizes the food-production process by catching vitality from the sun. Damage to leaf structure by air pollutants causes damage to chlorophyll, and without chlorophyll, a plant can't produce food or energy. In zones with broad groupings of ozone, portions of the leaf will bite the dust because of presentation. Other than damage to leaf structure by air pollutants causes, the additional air pollutant causes are delayed flowering, root damage and stomata damage.
