the answer is yes.
Because plants are conscious, there will be emotions when they are conscious, and there will be sadness when they have emotions. Perhaps most people will disagree, but science will eventually prove it.
From a biological point of view, plants have no brain or nerve tissue, so they will not have what humans call consciousness like animals. The consciousness of plants should be significantly different from that of animals called by human beings.
When it comes to plant consciousness, people usually think of mimosa. When human beings touch it gently, mimosa will fold its leaves. This reaction should be controlled by the plant's consciousness, and its purpose is to seek advantages and avoid disadvantages. Another example is that the venus flytrap will quickly cover the leaves when the insects enter its cage-shaped leaves, and the insects become a nutritious food for it.
So, like animals, plants have the same characteristics of seeking advantages and avoiding disadvantages as all living things. This feature allows plants to respond to changes in the external environment and dangerous factors, although it should not be as fast and obvious as animals. The instinctive characteristics of plants must be controlled by the consciousness of plants that have not been recognized by human science. Of course, with the development of science in the next few years, there will definitely be a scientific explanation for the problem of plant consciousness.
