Explain why plants communicate with each other through biochemical signals.

In short (click here for detailed version)

Plants communicate with each other through biochemical signals to exchange information about environmental conditions, such as predator attacks or climate changes, in order to trigger adaptive responses.

In detail, for those interested!

Enhancement of stress response.

Plants communicate with each other through biochemical signals to enhance their response to environmental stresses. When a plant is exposed to stress such as drought, predator attacks, or disease, it releases volatile chemical compounds that can be detected by other neighboring plants. These biochemical signals can activate the defense mechanisms of the receiving plants, preparing them to better respond to stressful conditions. This interplant communication allows plants to better adapt to their changing environment, thus enhancing their survival and growth. Plants use biochemical signals to coordinate and protect each other against the various stresses they face.

Transmission of information on pests

Plants have the ability to detect the presence of pests through biochemical signals. When a plant is attacked by insects or other harmful organisms, it can emit volatile compounds to warn other plants in the vicinity. These compounds act as alarm signals, allowing neighboring plants to prepare for a possible attack. This communication between plants about the presence of pests can be beneficial for the entire plant population, promoting a coordinated response and better resistance to external aggressions.

Symbiotic interactions with other organisms

Plants can establish symbiotic interactions with various organisms, such as fungi and bacteria. These beneficial relationships can help improve the health and growth of plants in various ways. For example, plants can form symbiotic associations with mycorrhizal fungi. These fungi colonize the plant roots, forming structures called mycorrhizae. This association allows plants to increase their ability to absorb water and nutrients from the soil, which can promote their growth and development.

Furthermore, some plants are capable of forming symbiotic associations with nitrogen-fixing bacteria, such as rhizobia. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can use, which can help improve the nitrogen nutrition of plants. In return, plants provide bacteria with a favorable environment for their growth, creating a mutually beneficial partnership.

Symbiotic interactions between plants and other organisms can also play a role in protection against pathogens. For example, some plants can establish symbiotic associations with bacteria or fungi that produce antimicrobial compounds, helping to combat pathogens and strengthen plant resistance to diseases.

In summary, symbiotic interactions between plants and other organisms are important mechanisms that can help improve the health, growth, and resistance of plants in their natural environment.

Coordination of growth and development

Plants are able to coordinate their growth and development through biochemical signals. These signals allow different parts of the plant to communicate with each other to ensure harmonious and efficient growth. For example, the plant hormone auxin acts as a key regulator by controlling the growth of plant tissues through promoting cell elongation and regulating root formation. Plants can also use biochemical signals to coordinate flowering, fruiting, and senescence. This coordination is essential to maximize the survival and reproduction of plants in changing and sometimes hostile environments.
