The change of seasons always makes people marvel at the magic of nature. From the green leaves of spring to the yellow leaves of autumn, this process is full of vitality and vitality. Let's explore this mystery of nature together and feel the beauty brought by the change of seasons.
Leaves turned greenIn spring, everything revives, and the earth is draped in green. In this season, leaves begin to sprout and gradually become fresh and green. According to "Flora Sinensis", there are more than 30,000 species of plants in China, among which there are many ornamental leaves. These leaves shine in the sunlight, adding endless vitality to nature.
1. The growth process of leaves
From germination to maturity, leaves need to go through multiple stages. The apical meristem begins to divide, forming new buds. Subsequently, the buds develop into young leaves, which gradually turn green. When the young leaves grow to a certain size, they begin photosynthesis to provide nutrients for the plant.
2. The function of leaves
Leaves are important organs for plants to carry out photosynthesis, capable of converting sunlight into energy needed by plants. Leaves can also absorb water and carbon dioxide and release oxygen, maintaining the carbon-oxygen balance in the atmosphere.
Leaves turned yellowIn autumn, as the temperature gradually decreases, leaves begin to turn from green to yellow, a process called "defoliation". According to the "Chinese Forestry" magazine, about 100 billion kilograms of leaves fall in northern China every year, providing the soil with abundant nutrients.
1. The reason why leaves turn yellow
Leaves turn yellow mainly due to factors such as the decrease in temperature and the shortening of daylight hours. When the temperature is lower than 15°C, the decomposition rate of chlorophyll in the plant body accelerates, causing the leaves to turn yellow.
2. The benefits of defoliation
Leaves provide the soil with abundant nutrients, which is beneficial for plant growth. Leaves can also increase the organic matter content in the soil and improve the soil structure.
The scene after the leaves turned yellowIn autumn, when the leaves turn yellow, the earth presents a golden hue. In this season, people flock to nature to appreciate the beauty of autumn. Here are some common autumn scenes:
1. Maple leaves turned red
Maple leaves are one of the most representative autumn scenery. When the maple leaves turn from green to red, the whole mountain seems dyed red.
2. Oak leaves fall

Osmanthus is the unique fragrance of autumn, with its flowers exuding a strong aroma that intoxicates people.
