Answer 1

The sensation is the process of detecting environmental stimuli and converting them into signals that can be detected by the nervous system.

In biology, the classical belief of the nervous system determines that it's a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from totally different elements of its body. The systema nervosum detects environmental changes that impact the body, then works in wheel with the endocrine system to answer such events. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.

However, this classical doctrine has been challenged in recent decades by discoveries concerning the existence and use of electrical signals in plants. On the premise of those findings, some scientists have projected that a plant nervous system exists which a scientific field referred to as plant neurobiology should be created. This proposal has a crystal rectifier to a dispute within the scientific community between those that assume we should always say the systema nervosum of plants and people who are against it.
