Скачать или смотреть Photosynthesis, Transpiration and Gas Exchange in Plants

This video features an educational song that clearly and integratively explains photosynthesis, transpiration, and gas exchange, three essential processes in plant physiology and in sustaining life on Earth. The lyrics show how these mechanisms work together to ensure energy production, water transport, and gas balance in plants.

The song begins by explaining photosynthesis, a process that occurs in the chloroplasts and converts light energy into chemical energy. It describes the light reactions, responsible for producing ATP and NADPH and releasing oxygen, and the dark reactions (Calvin Cycle), in which CO₂ is fixed to form carbohydrates such as glucose.

Next, the lyrics address transpiration, the loss of water vapor through leaves, mainly via the stomata. This process is essential for water movement within the plant, temperature regulation, and maintaining internal pressure in plant tissues.

The video also explains gas exchange, showing how CO₂ enters the leaf for photosynthesis and how O₂ is released into the atmosphere. The song highlights the regulatory role of stomata, which balance gas exchange according to environmental conditions.

With engaging rhythm and clear scientific explanations, the video turns key concepts of plant physiology into accessible and memorable learning, making it ideal for students, educators, and anyone interested in understanding how plants support life on Earth.
