fall into winter

There were several main reasons why all the leaves fell in winter: 1. The role of plant hormones: Abscisic acid, a plant hormone, exists in plants. With the arrival of autumn, the sunshine time is shortened, and the temperature is lowered. Abscisic acid is produced in large quantities and transferred to the relevant parts, promoting the production of the base layer of the petiole, causing the leaves to fall off. 2. Dealing with the cold: The leaves contain water. When the temperature drops to one or two degrees at night and gradually rises during the day, the leaves will turn yellow and red. When the temperature drops below zero, the water in the leaves will freeze. After repeated tossing and turning, the leaves will freeze to death and fall in the wind. 3. Reduce water loss: Leaves are the organs of trees for photosynthesis and the main way for water to evaporate. In winter, the sunlight was short, the photosynthesis was weakened, and the water supply was insufficient. If the leaves were retained, it would cause excessive water loss and even death from dehydration. In order to reduce the loss of water and protect the trunk from dying in the dry winter, trees would shed their leaves. Before autumn came, decidual-leaf trees would transfer the organic matter in their leaves to the roots, stems, and buds for storage. At the same time, a separation layer would form between the petiole and the branches, cutting off the connection between the petiole and the branches, causing the leaves to gradually wither, change color, and fall off. After the leaves fell, the decidual-leaf tree entered a dormant state, reducing the rate of metabolism and saving energy consumption. It also used the stored organic matter to maintain basic physiological functions and promote the development of buds and flowers. When spring came, it would wake up and grow again.

The main reasons for the leaves falling in winter were as follows: 1. Phytohormone effect: Abscisic acid, a plant hormone, exists in plants. With the arrival of autumn, the sunshine time is shortened, and the temperature is lowered. Abscisic acid is produced in large quantities and transferred to the relevant parts, promoting the production of the base layer of the petiole, thus causing the leaves to fall off. 2. Reduce loss: It is a normal physiological phenomenon for trees to lose their leaves. After the leaves fall, the trees can reduce the loss of water and nutrients, and transport the nutrients to the roots, stems, and buds for storage, and then enter a dormant state to cope with the cold in winter. 3. Drought-adapted: The winters were relatively dry, and the trees abandoned their leaves in order to reduce their water absorption and supply more water to the main trunk and branches. 4. [Resist the cold: Cold weather has a direct impact on the leaves. Falling leaves is also a way for trees to protect themselves.] "Life Like a White Birch" is equally exciting.

Climbing flowers that did not fall leaves in winter included ivy, viburni, spider plant, myrtle, fortunei, stargall vine, thyme pea, triangle plum, agave, clematis, and so on. These flowers would not lose their leaves in winter, so they could maintain their green color and have ornamental value. They had strong adaptability and exuberant vitality. They could grow indoors and could also decorate the environment and purify the air.

Fall winter Christian comic strips often focus on themes of hope, faith, and reflection during the colder seasons. The styles can range from traditional to modern, with detailed illustrations or simple yet powerful imagery.
