Generally, cognition, traditionally associated with animals and humans, involves processing information and responding to stimuli. In plants, cognition is redefined to include nonneural methods of information processing. Plants exhibit behaviors that involve some form of cognition, such as modifying growth patterns in response to surrounding environmental changes. Despite lacking a central nervous system, plants show the ability to manage and respond to triggers.

Plants have well-developed mechanisms for sensing their environment. Through specialized cells and structures, they detect light, gravity, water, and chemical signals. For example, photoreceptors allow plants to sense the intensity and direction of light, while root cap cells detect gravity and guide root growth. This sensory information is essential for plant survival, as it enables them to improve access to resources and adapt to environmental fluctuations.

Learning in plants involves changes in behavior based on experience. Studies have shown that plants can modify their responses to repeated stimuli. A notable example is Mimosa pudica, a plant that folds its leaves when touched. Over time, if touching is harmless, the plant learns to conserve energy by not closing its leaves. This adaptive behavior refers to a basic form of learning, challenging the idea that it is limited to animals.

Memory in plants manifests itself in their ability to "remember" past events and adjust future behavior accordingly. Plant memory is embodied in vernalization, a process in which plants require a cooler period before flowering. This ensures that flowering occurs at the optimal time, which enhances the success of reproduction. These memory mechanisms highlight a plant's ability to store and retrieve information, contributing to its adaptive strategies.

The exploration of botanical perception dates back to the early twentieth century, with pioneers such as Jagadish Chandra Bose, who demonstrated that plants respond to different stimuli. Despite the doubts, his work laid the foundation for modern research. In recent decades, advances in molecular biology and genetics have provided deeper insights into plant behavior, reinforcing the concept of plant perception. This historical perspective confirms the evolving understanding of the plant world and the growing recognition of plants as dynamic organisms.

Recognizing botanical perception pushes ethical considerations regarding human interaction with plants. As plants have shown forms of learning and memory, this raises questions about how they are treated in agriculture, horticulture and environmental conservation. Should more respectful practices be adopted? This is linked to ethical implications, and calls for a shift towards sustainable and thoughtful interactions with plant life.

Due to the cognitive abilities of plants, humans must adopt practices that reflect respect for and care for plant life. This includes:

Sustainable agriculture: The use of farming techniques that preserve the health of soil, water resources and biodiversity, ensuring long-term agricultural productivity without harming the environment.

Conscious gardening: Engage in gardening practices that take into account the needs of plants, such as proper watering, pruning, use of natural fertilizers and pest control methods.

Conservation efforts: Protect habitats and endangered plant species through conservation initiatives and policy support that mitigate deforestation and habitat destruction.

Education and awareness: Promote awareness about botanical knowledge and the importance of plants in ecosystems, and encourage people to appreciate and respect plant life.

This section emphasizes the importance of integrating ethical and sustainable practices in interacting with plants, recognizing their intrinsic value and cognitive abilities.

The field of botanical perception is evolving rapidly, as new discoveries are constantly rethinking plant understanding. Future research aims to uncover the molecular mechanisms underlying plant behaviour, which could lead to innovations in agriculture and biotechnology, and to chart future directions and potential applications for plant perception research, with a focus on the need for interdisciplinary collaboration.

While plants may not possess brains in the traditional sense, they exhibit remarkable cognitive abilities that challenge humans' perception of intelligence and behavior in the natural world. Understanding botanical perception not only enriches knowledge of plant biology, but also calls for a reconsideration of humans' relationship to the plant kingdom. As the mysteries of vegetative perception continue to be revealed, the complexity and interdependence of all life on Earth can be recalled.

Delving into the complexities of botanical perception, sensation, learning, and memory, this article highlights the deep potential of plants and the importance of promoting coexistence with the natural world.
