What is a photochemical smog?
Photochemical smog forms when certain pollutants in the atmosphere react with sunlight. It mainly consists of ground-level ozone (O3), mixed with other toxic gases and particulate matter. This type of air pollution typically plagues urban areas, especially in cities with high levels of vehicle and industrial emissions. Here’s how photochemical smog forms: Emissions: It all…
Q&A on plant structure and function
Q: What is the primary function of plant leaves? A: The primary function of plant leaves is to perform photosynthesis, where they convert sunlight, carbon dioxide, and water into glucose and oxygen. Additionally, leaves also facilitate gas exchange and transpiration. Q: How do plant roots contribute to the overall health of a plant? A: Plant…
Plant structure and function
Let’s delve into more detail about plant structure and function: Plant Structure: Roots: Function: Roots have several essential functions, including anchoring the plant in the soil, absorbing water and minerals, and storing carbohydrates. Types: Taproots: A single, large, central root, typical in dicotyledonous plants. Fibrous roots: A network of fine, slender roots, common in monocotyledonous…
Enzymes: Substrate Interaction & Biochemistry
Within the realm of biology, cells rely on intricate processes to sustain life. Catalysts known as proteins play a crucial role in these processes, expediting chemical reactions.
