can plants see?

Answer 1

There is no doubt that plants can sense light. They can determine the intensity and direction of it. They can react to changes in light, sometimes rather rapidly. They have a substantial number of organs specifically designed to detect and react to light. They are capable of detecting a variety of frequencies of light and distinguishing between them. They are capable of distinguishing between the presence of some objects and others.

They cannot perceive images. They lack any ability to think or react intelligently to the information their light-receiving organs receive. They can't not-receive light to any great degree.

Whether they 'see' or not is going to depend on what you consider to be 'seeing'. They certainly can interact with light in a meaningful way. That certainly cannot do so with any kind of intelligence.

Me... I'd say they do see. But not even vaguely like you or I do.

Answer 2

No, they can hear, and sense movement and other things like heat. But they can not see. They go by feeling things, like if you put a plant near a window, the plant will move towards the sun because of the light and the heat that comes with it.

Answer 3

Sight implies that there is a mental interpretation of the images, and since plants do not have the equipment necessary for interpretation (a nervous system), I would have to say, no, plants can't "see". They can however respond to changes in light.
