The immobility of plants is consistent with their principal function: collecting
light to provide photosynthetic substrate for the biological system. Their
immobility does impose limitations on some basic requirements, such as the need
for pollination, for seed dispersal, and for protection against herbivores.
Meeting these 3 needs will logically necessitate some ability for plant
communication - at least a capability for beneficial adaptive behavior. Three
types of plant behavior provide evidence of memory and communication abilities: a
capability for memory, a capability for measuring time, and extensive evidence of
chemical signaling systems. These may provide benefits for genetic outcrossing,
seed dispersal and protection - beneficial adaptive behaviors. The chemical
signaling system constitutes a wireless communication network that draws mobile
animals into assisting plant functions that require mobility. Plants share their
chemical signaling systems most frequently with insects and birds. These
beneficial adaptable behaviors may be interpreted as some type of consciousness.
