The Persistence Of Memory
A Polish study showed plants send electrochemical signals in a way that
can be likened to an animal nervous system. This image shows chemical
reactions in leaves that were not exposed to light; they are reacting to
a chemical signal from a leaf that was exposed.

This article really made me think. It seems logical that plants can think and remember stuff like light patterns, but it is still really cool. This article was talking about a lot of stuff we learned in our plant unit. About vascular tissue especially. This article also said that shining light on a plant can have any number of effects, which is a lot like a human's mind. Doing something can cause a various number of effects based what kind of plant it is, what season it is, if they are thirsty, and so on and so forth. The article says that some tests said that the shining light thing transmits the electrical impulse. The logic of how plants can remember is one that should be remembered. This was a fantastic article!
I think this article was really good because i thought it was really interesting that plants may be able to think. I thought it was really cool that if you shine light on a plant it affects it, like if you hit your head it affects your head.
This article is really cool and interesting. I thought is was really cool that plants are able to think and "remember" things. The article said shining light had many effects. we just learned a lot about plants in class, so it is nice to know more about plants and leaves.
I agree with Rachel. This was really interesting. I did not know that there was a cabbage relative capable of remembering light sources as it did in the experiment! I t was really cool that the plant created this reaction to a light source the remembered it after the light was put away. I don't understand somethings. How did the plant send electric signals? It was fun to relate the plants in this experiment and see the difference to the ones we learned about in class.
I don't think plants can actually remember the light. I think it is just lingering kind of with them.
This article was cool, but a bit confusing.
It was confusing because...
How do we know that this works on all plants if in one of the first paragraphs it states that the leaves take in the sunlight and remember the quantity and strength of the sunlight, but does this work on non-vascular plants, I mean, they don't have any leaves.
I thought it was cool because again, like I said in my comment on the fern spores, finding out that these immobile things can think, like they have some kind of a brain like an animal...that's crazy.
The article was overall pretty good except for the fact that I noticed that one of the scientists made a mistake.
In the third to last paragraph, the writer says that a scientist claims that a plant can't just move to a sunnier or different place, so plants have to make the most of their environment. Which from what Ms. Ghazarian taught us, isn't true. Plants can't physically walk to another place, but if their seeds are able to grow farther, and farther away from the original plants, and each one of these new plants can make small adaptations to a new environment, there can be some of the same plants in many different areas if the plant is able to survive.
Otherwise, I thought that this article was very cool, but a bit freaky. To know that these things that we believe to be just for decoration, or just immobile objects we can sell, and then find out that they can think! That's awesome!
This is a very interesting article. I don't think that plants can think. I is amazing that they can remember and react to certain things. It has some relations to the human mind in someways. The was a great article!
I think that it is so cool that plants can remember. I forget light quality and quantity immediately. That is an amazing article.
I think that Finn has a good point. Maybe it is just a coincidence and that is why the reaction did not stop.
OK. So, now plants can't think, but they can remember? Um, what's the difference? I get what they're trying to say. The plants respond to different qualities and quantities. I don't think that humans even analyze that. So I guess that plants can only remember the things that help them. I can understand why they would do this. But what if two plants are touching? Do they share thoughts? Or do they just recognize it as another plant nearby? Can they even sense touch? What about if you pick a leaf? What happens then? Also, some plants work with animals to help them both. Can the plant somehow know this? There are also some plants that move. Do these plants have better memory? This article was really cool, but I think the scientists should have experimented more before publishing it.
