What are the biological clocks of plants?
The biological clock of a plant was an internal time sensing system that had many manifestations: 1. Controlling the sleep movement of plants, such as red clover, when night fell, the three small leaves folded together and lowered their heads to sleep. This change of day opening and night closing repeated for about 24 hours, even in complete darkness. 2. Plant dormancy is a state in which plants enter a state of slowing down their growth and metabolism to save energy and cope with harsh environmental conditions. Dormancy usually occurs at night or in the cold season. The biological clock can be based on the light cycle of the environment (The ratio of light to dark period in a day) and other factors (such as temperature, hormones, etc.) to adjust the plants to enter or leave the dormancy state. For example, some plants adapted to short sunlight conditions (longer dark period) would enter the dormancy state during the long night or the long dark period in winter. Some plants adapted to long sunlight conditions (longer light period) grew in the long white sky in summer, and the biological clock ensured that the plants would switch these states at the appropriate time. For example, the hormone gibberellin promoted growth while suppressing dormancy, and the hormone abscisic acid promoted the formation of dormancy. The biological clock also played a role in the regulation of this hormone. At the same time, the cold temperature caused plants to enter dormancy, which was also affected by the biological clock. 3. Controlling the blooming time of plants. Different plants 'blooming was controlled by the biological clock and had a certain time pattern. For example, Linnaeus discovered that the blooming time of various plants was restricted by the biological clock. The blooming time was related to the pollinators that were active at different times. Plants that bloomed during the day attracted pollinators such as bees, butterflies, and birds, while plants that bloomed at night attracted moths and bats. 4. It controls other biochemical activities of plants, such as the blooming of flowers, the production of fragrance and nectar, the secretion of tree sap, and the dormancy of leaves.

What are the natural biological clocks?
The natural biological clock was an invisible " clock " in the body of an organism. It was the intrinsic rhythm of the biological activity. It was mainly determined by the Earth's revolution around the sun, the Earth's rotation, the temperature changes on the Earth's surface, and the cycle of day and night. The moon's revolution around the Earth also had a certain impact on it, but it was not significant. In the biological world, the natural biological clock had many manifestations. For example, all animals had a 24-hour cycle from day to night. For example, human sleep, wakefulness, and eating behavior were all controlled by the biological clock. Many natural rhythms in the human body, such as physical strength, intelligence, mood, blood pressure, and menstruation, were also regulated by the biological clock. For plants, bamboo shoots could break out of the ground at the same time. The sprouting of vegetation, the growth of green leaves, the blooming of rice flowers, the ripening of fruits, the fall of leaves, the fragrance of fruits, and other phenomena were all related to the biological clock. In other words, when to sprout, when to bear fruit, when to grow leaves, when to fall leaves, and so on were all determined by the biological clock.

What are the biological clocks in nature?
There were two main types of biological clocks in nature. One was the biological clock of the whole body, such as the main biological clock in the human brain, which controlled the life activities of the whole body such as the day and night rhythm. The other was the biological clock of different organs and tissues in the body, such as the local biological clock of the human joints and spine.

Other biological clocks in nature
The biological clock was an invisible " clock " in the body of an organism. In fact, it was the internal rhythm of the biological activity, determined by the time structure of the biological body. Other than humans, many creatures in nature have biological clocks. Plants have biological clocks. For example, the flowers of some plants would open and close at a specific time, such as morning glory. This was the response of its biological clock to environmental factors such as light and temperature, and it carried out physiological activities according to a certain rhythm. Animals also had biological clocks. Many birds had the habit of seasonal migration, which was an adaptation of their biological clock to seasonal changes, food resources, and other factors. They began to migrate at a specific time every year, flying long distances to another area in search of a more suitable living environment. There were also some night-time animals, such as owls, whose physiological activities were more active at night and rested during the day. This regular work and rest was also a manifestation of the biological clock. Insects also had biological clocks. Bees 'honey gathering activities had specific peaks during the day, which was related to the physiological state of their biological clock regulation to adapt to the timing of nectar secretion. These biological clocks help organisms adapt to the periodic changes in nature, such as the alternating of day and night, seasonal changes, etc., and are of great significance to their survival and reproduction.

What are the biological clocks in nature?
Here are some biological clocks in nature: 1. ** Human body biological clock **: There is a biological clock in the human body that controls the human organs and causes the human organs to show a natural rhythm. For example, as a human organ, the skin's metabolism followed the human body's biological clock. During nighttime sleep, especially from 12 midnight to 6 am, the metabolism was the most active and vigorous. At this time, cell growth and repair were the most vigorous, and the cell division speed was several times faster than usual. Moreover, when people were sleeping, their whole body was relaxed, and their skin pores were open, making it easier for them to accept the nourishment of skin care products. 2. ** epigenetic clock **: estimates the age of an animal based on life events such as stress or diet. When animals experience a lot of trauma, their epigenetic age (biological clock) may be much older than their actual age. Some creatures stop this key aging mechanism at the age of four. 3. ** telomere (can be regarded as biological clock)**: Its length is a "biological marker" that reflects a person's aging speed and cell repair and regeneration ability. For example, smoking will cause white blood cell telomeres to shorten and accelerate aging, while quitting smoking will delay aging.

What are the living clocks of animals and plants?
The hop used to make beer bloomed at around three o'clock in the morning and withered at eight or nine o'clock. The morning glory turned on the horn at about four o'clock in the morning and closed at noon. At five o'clock, the wild rose smiled. At six o'clock, the dandelion and the nightshade nodded with a smile. At seven o'clock, the peony began to compete for beauty. The noon flower bloomed at noon. At six o'clock in the afternoon, the loofah opened its petals. After sunset, the evening primrose began to breathe. The novel " The Name Engraved in the Stars of Destiny " is equally exciting.

Take a few examples of biological clocks
Here are some examples of biological clocks: - Humans were awake for about 16 hours and asleep for 8 hours every day. The changes in sleep and the sometimes confused state of a person were affected by the biological clock. A woman's menstrual cycle was a kind of circadian rhythm. Before and after menstruation, body temperature, hormones, appetite, and emotions would change regularly. - In terms of animals, the Dina bird in Guatemala, South America, would chirp for a while every 30 minutes, with a time interval error of only 15 seconds; the time worm in the African jungle changed color every hour; these could be used by local residents to calculate the time. - In the field of plants, there was a wildflower in Argentina that bloomed around 8 p. m. in early summer, and there was a large-leaved tree in South Africa that flipped its leaves every two hours. - Among the ancient creatures, there were traces of tree "growth rings" on the surface of many types of ancient creatures, recording their growth information at that time. They could be used by scientists as timers of geological time. For example, fossils such as corals, bivales, and stromatolites were preserved to reflect the characteristics of periodic growth changes (biological rhythms).

What are the life clocks?
The life clock had the following meanings: First, it referred to Lifeclock, which was a social network that recorded one's life journey, showed one's true self, and advocated people to pursue a natural, harmonious, and healthy life. Second, in the concept of comparing life to 24 hours, different ages corresponded to different times in the life clock. For example, 25 years old was converted to 7:30 in the morning. Third, telomere shortening was called the life clock by scientists. In addition, some people used the life clock to describe the countdown of life. For example, when a loved one was seriously ill, the life clock was counting down. The novel " The Name Engraved in the Stars of Destiny " is equally exciting.
