Plants are responsive to external stimulation, though their system and response is different from animals.

Touch the "Touch me not" plant, you can observe their quick effects. The carnivorous plants like Venus fly trap can capture and digest flies.

Many works of famous scientist Prof. Jagadish Chandra Bose are there on that topic.

I think plants have also consciousness, though of different types.Same can be said about bacteria etc. lower species.

Thanks.

If you consider consciousness as response to the environment, then plants without any neural system also show responsiveness in various ways.

A green plant grows towards sunlight.

A leaf of a Sundew plant immediately starts movements of the tentacles to catch a fly as soon as it senses landing on its leaf.

I think the Cell is the smallest unit of life with consciousness and everything between the Cell and the fundamental particles of physics have life but no consciousness.

Dear Vikram Zaveri, your manuscript is so wonderful. Thanks a lot.

Dear Sebastian Schmitt, thank you for the response. That is exactly my problem.

Should we consider the consciousness as a neural event?

Dear Subir Bandyopadhyay

According to your definition of consciousness and due to the viruses are not the alive organism, can we tell a virus is a conscious multimolecular material?

Please pay attention to this video...

Excellent video Pooriya.

Kindly see the discussions in the given links too:

Dear Subir Bandyopadhyay

Tapan Mukherjee has said: "It will be observed that body immune system is defeated by more intelligent moves of virus. This is not possible without lifting of consciousness levels within a virus."

That's so fascinating...

Regarding the cycle of virus replication and behavior of Sundew plant, I do not think that consciousness only occurs in the nervous system.

As it seems, programmer and stimulant of emerging consciousness are genetic sequences.

Do you agree with this theory?

Dear Pooriya:

Thank you for this fascinating query. I have no in depth study in this field and so like see comments from experts.

Thank you once again.

With best wishes,

Subir.

I agree with Prof. Shibabrata. We can't rule out consciousness entirely for other living things aside from human beings. I agree that some plants have consciousness. We need to comb studies into other life-laden creatures for possible signs of consciousness. Best regards

Dear Shibabrata Pattanayak and other friends

As it seems, we are faced with a huge paradox in response to most questions about the consciousness. There are many different ideas about the existence of consciousness in animals, plants, fungi, and Microorganisms. I think this subject is strongly dependent on the human definition of consciousness. Some researchers find the reaction of plants and microorganisms to their surroundings only as a result of chemical interactions.

They say that the plants do not have any perception and awareness of hunting act. for example on Wikipedia has been told about animal consciousness:

"The topic of animal consciousness is beset by a number of difficulties. It poses the problem of other minds in an especially severe form, because non-human animals, lacking the ability to express human language, cannot tell us about their experiences. Also, it is difficult to reason objectively about the question, because a denial that an animal is conscious is often taken to imply that it does not feel, its life has no value, and that harming it is not morally wrong. Descartes, for example, has sometimes been blamed for mistreatment of animals due to the fact that he believed only humans have a non-physical mind. Most people have a strong intuition that some animals, such as cats and dogs, are conscious, while others, such as insects, are not; but the sources of this intuition are not obvious, and are often based on personal interactions with pets and other animals they have observed."

But some other researchers, such as David Chalmers, believe that consciousness and space and time have fundamental ties.

I'll be glad if you see this video and share your opinions with me.

Thank you, dear Dickson Adom. I agree with you.

We need to comb more studies.
