What factors affect the perception of plants?
factors affecting plants include light, sound, touch, humidity, temperature and magnetism. Plants recognize and adapt to changes in the cellular environment through complex interactions of genes and receptors that identify external stimuli. Study of plants perception has gained international interest in dealing with population growth and climate change affecting food production. These cells communicate at the molecular level through genes that respond independently or in tandem to adapt and allow survival. Scientists have successfully insulated specific receptors that regulate certain stimuli, but the complicated process is not fully understood.
Plant perception includes light sensors to determine the day from the night and identify harmful ultraviolet rays. Three photos receptors cooperate and adapt to the environmental light of the narrow growth phases, including germination, flowering and a sleeping stage. Molecular adaptations also produce pigments for filtering ultravioletThey create natural sunscreen.
Biocommunication in plant cells promotes plants perception when insects, bacteria or fungi represent a threat. Some plants produce toxin that kills infected cells to prevent damage from spreading. They could create a smell that warns about the threat plants, allowing them to start producing toxins. A similar process increases certain acids to avert the parasitic plants that attack the environment.
plants perception also triggers a response to touch, sound and magnetic fields. The hormone called gibberrelic acid may affect the growth rate of plants exposed to certain wavelengths, frequencies or vibrations. Plants also adapt to wind by growing stronger or more flexible. In one study on magnetism, the roots of plants grew towards the source, while the stems grew in the opposite direction.
Plant perception studies show that the network of genes interacts for more efficient use of water when water is rare. One of these genes reduces the water transpiration speed into the air over leaves and stems. The same process could allow plants to withstand saltiness in water and use nutrients more efficiently. Scientists believe that these defense mechanisms reduce crop yields due to the energy needed to create short -term adaptations or molecular changes.
The perception of plants differs from perception, the belief that plants have emotions capable of registering fear, pleasure and pain. These concepts became popular in the 1960s, when American researcher Cleve Backster connected detector devices to plants. He argued that he claimed paranormal biocommunications between plants and humans. This theory is not considered scientifically valid, so they lack the central nervous system and the backster results cannot be replicated.
