Question

what is chemical communication in plants and animals ? explain briefly I will mark the best answer brainliest

Answer 1

There are numerous excellent books about plant–pollinator and plant–herbivore interactions, and books about plant defence, but none of these covers the process of communication between plants and animals as comprehensively as this volume. The authors define communication as occuring ‘if traits of the sender stimulate the sensory systems of the receiver in such a way as to cause a change in the behaviour of the receiver’. In most cases the signal – visual, olfactory, gustatory or acoustic – is released by the plant.

The focus in this book is on olfactory and visual signals. In addition, the authors give examples of how insects can detect plant quality just by walking on it and sensing the taste with gustatory sensors in their legs. Acoustic communication is exemplified by the noise of fruit falling into water, where fruit-feeding fish are alerted to this food source, eat the fruit and subsequently disperse seeds. Acoustic communication is also linked to bat-pollinated plants, which have mirror-like structures in their flowers to strongly reflect bat echolocation calls back to the sender.

The authors have taken an evolutionary ecological approach, setting the key questions of whether communication between plants and animals is primarily adaptive or whether it is a by-product of other selective pressures. The book has eleven chapters, including ones on animal sensory ecology and biochemistry, animals as seed dispersers, visual and non-visual fruit traits, floral communication and pollination, plant crypsis, aposematism and mimicry, chemical communication between plants and herbivores, and sensory aspects of carnivorous plants.

Answer 2

Hey mate!! <3
here is your answer

Capabilities of organisms and their roles can be viewed from two aspects : social relation for the maintenance of ontogeny and social relation for the maintenance of phylogeny. Chemical communication capabilities of organisms and their roles can be seen in a similar way. Because higher plants are sessile organisms, they utilize physical phenomena such as wind and water, and organisms such as insects, birds, or mammals for their mating and dispersal of seeds to maintain their lineage. Their form of evolution has been unique and different from that of animals. Their functions for mating include perfume, flowering season, flower form, flower color, nectar ; the functions for dispersal are perfume, fruit form, sarcocarp, and elaiosome.
