In the bustling city, as night falls, people enter their dreams, while plants in the natural world do not rest. They begin their own secret life in the seemingly silent night. What wonderful behaviors do plants have at night? This article will take you on a journey of discovery.
Photosynthesis "Night Version"It is well known that plants perform photosynthesis during the day, absorbing carbon dioxide and releasing oxygen. At night, due to the lack of sunlight, photosynthesis seems unable to proceed. However, in fact, plants also undergo a process similar to photosynthesis at night, known as "nocturnal respiration."
Nocturnal respiration refers to the process by which plants release carbon dioxide and absorb oxygen through respiration at night. Although this process is not as significant as photosynthesis during the day, it is still of great importance for plant growth and development. Nocturnal respiration helps plants regulate the concentration of oxygen and carbon dioxide in their bodies, maintaining normal life activities.
Plants' "Nocturnal Dialogue"Plants engage in a special "dialogue" at night, which is the transmission of information through chemical signals. These chemical signals include plant hormones, volatile organic compounds, etc. Studies have found that plants release some volatile organic compounds at night, such as jasmonic acid and ethylene. These compounds can convey information about plant growth status, diseases, and pests.
When plants are attacked by diseases and pests, they release chemical signals containing jasmonic acid, attracting other plants to produce defensive responses. This "nocturnal dialogue" helps plants in the natural world to cooperate with each other and jointly resist external threats.
Plants' "Nocturnal Movement"At night, plants perform some special movements, such as the closure of leaves and the opening of flowers, which help plants adapt to the nocturnal environment, reduce water evaporation, and decrease energy consumption.
1. Leaf Closure: At night, the leaves of plants gradually close to reduce water evaporation. This closing movement helps plants maintain water balance at night and avoid affecting growth due to excessive water loss.
2. Flower Opening: Some plants' flowers open at night, such as night-blooming flowers and moonlight flowers. The opening of these flowers helps attract nocturnal insects, such as moths and bats, thereby achieving pollination.
Authoritative Report InterpretationAccording to the Journal of Plant Physiology, the growth and development of plants at night are influenced by various factors, including light, temperature, humidity, etc. Studies have shown that the growth rate of plants at night is slower than during the day, but physiological activities such as nocturnal respiration and chemical signal transmission are still very active.
Researchers at the Institute of Botany, Chinese Academy of Sciences, have found that plants release a chemical substance called "plant hormones" at night, which can promote plant growth and development. This study provides new theoretical evidence for the regulation of plant physiological activities at night.
The wonderful nocturnal life of plants fills us with awe for the magic of nature. By understanding the physiological activities of plants at night, we can not only better protect plants but also provide more assistance for their growth and development. In future research, scientists will continue to explore the mysteries of plant life at night, creating more benefits for humanity.
