Plants sleep at night!! Most leguminous plants close their leaves in the evening, as if to sleep, and open
them early in the morning according to the circadian rhythm controlled by a biological clock.
Extensive studies on nyctinastic plants led to the isolation of a variety of leaf-closing and
-opening substances. And we found that the biological clock regulates the balance of concentration
between leaf-opening and -closing substances in the plant body during the day.

There for: Based on the mechanism of leaf movement we hypothesized that a structurally modified leaf-opening factor that cannot be
hydrolyzed by glucosidase by would inhibit leaf closure, keeping the leaf open constantly in a condition
we call “insomnia” Potassium lespedezate is a glucoside-type leaf-opening factor.
Structure–activity relationship studies have shown that structural modification of the sugar moiety of 7
causes no decrease in bioactivity. Based on the structure of 7, we designed and synthesized potential
leaf-closure inhibitor (14) containing galactose instead of glucose, which are not expected to be
hydrolyzed by β-glucosidase. Inhibitor 14 showed novel bioactivities in bioassays. Both 7 and 14 kept
leaves open, even at night, at 1 × 10–6 mol/l. When the leaves were treated with 3 × 10–6 mol/l of 7, the
leaf-opening activity lasted for only 2 days, after which the leaves again closed at night. This is because
7 is gradually hydrolyzed into its corresponding aglycon within a few days in the plant body. In contrast,
the leaf-opening activity of 14 lasted more than a week. Thus, we succeeded in inducing “insomnia”
in plant leaves. Insomniac leaves were damaged by inhibition of leaf closure, and withered and
died within two weeks. Using synthetic inhibitors of leaf closure to induce “insomnia” in plants, we
showed that nyctinastic leaf movement is essential for the survival of leguminous plants. These results
are the first experimental data of the importance of leaf closure for the survival of legumes, and provide
an important clue for solving the ancient mystery, “Why do leguminous plants sleep?”

It appears to me, from all the factual evidence, that applying the term "sleep" to plants is like applying the term "sleep" to a fan that has been turned off. It just doesn't apply. You can continue to bicker the matter but I'm not sure why someone would choose to waste more then a minute on a moot point.

Think I'll go put my fan to sleep now!

it amazeas me how u turned an intelectual debate into a day long rant of irrelevant oppinionated, bullshit! i understand u wur simply trying to get a point across but when u find litterally nothing to prove wur u are coming from its just oppinon! im sorry u are not capable of changing facts! i guess thats somethin u will have to live with but maybe there are some things that u can take away with u fom this thread! there are tons and tons of posts of good reads....some very far off topic, some being unsupported oppinons, and some being litterally a sentence and nothing more....but most being very good reads supporting the facts they cover! maybe u will from now on read and research be4 u bite off more than u can chew! everyone is entitled to oppinons that i am not disputing but these ppl here at RIU are aslo entitled to what matters more and that is the truth! u can throw daggers and call names all day long but the educated will know enough to see what is true or not. i just hope that one day u lose this egotistic, stuck up, ignorant, college boy know it all attitude and become humble and accept the facts and truths that are laid out be4! i wish u luck as u will not get very far if u do not change the way u see valid and factual information!

this my friend is the exact point the good ppl of this thread are trying to get across! time was waitsed in arguing this point so that the less educated dont stuble across the misinformation on threads such as this and interpret it to be facts! i call them out as i see em and i stand strong for what is not only right but true! and once again this kid is the only one in this thread that will suggest a plant sleeps at night....

once again..simple grammar is overlooked
lol i ahve also touched on the point that many of the authors in his links refer to the leaves as being in a sleeping state but still they use the word sleep only to communicate a meaning...and even so they are not talkin about the plant they are talkin abou the curling or drooping of leaves...

They need the dark for a reason and its to sleep!

man that clearly only saays closed leaves at night are sleeping says nothing of a plants processes only states a leaf that curls up to protect it self is sleepin...dnt quite see how they get that but once again if a plant is doing everything, if not more than it does during the day other than collect light, how can u state its sleeping? i really think tht u are poorly educated or just some lil kid! read it man they are referring to leaves closing as a sleeping leaf....they dont even say a sleeping plant lofl i swear u just research see sleep and leaf and are like oooo that prove s me right! lofl read it! it onyl proves that there is a system in a plant to tell it to open or close its leaves...that still is far from proving ur point!


and if ur really that clueless on what they do wen they sleep u can simply read every lst on of my posts tellin u and provng to u what they do and how its far from sleeping

as posted be4 this is one of the many reason as to why a plant needs a night peroid....and that def, dont sound like sleeping.......

The Calvin cycle (The Nonlight Requiring Reactions)



The Calvin cycle is a metabolic pathway found in the stroma of the chloroplast in which carbon enters in the form of CO2 and leaves in the form of sugar.

The Calvin Cycle The cycle spends ATP as an energy source and consumes NADPH2 as reducing power for adding high energy electrons to make the sugar. There are three phases of the cycle. In phase 1 (Carbon Fixation), CO2 is incorporated into a five-carbon sugar named ribulose bisphosphate (RuBP). The enzyme which catalyzes this first step is RuBP carboxylase or rubisco. It is the most abundant protein in chloroplasts and probably the most abundant protein on Earth. The product of the reaction is a six-carbon intermediate which immediately splits in half to form two molecules of 3-phosphoglycerate. In phase 2 ( Reduction), ATP and NADPH2 from the light reactions are used to convert 3-phosphoglycerate to glyceraldehyde 3-phosphate, the three-carbon carbohydrate precursor to glucose and other sugars. In phase 3 (Regeneration), more ATP is used to convert some of the of the pool of glyceraldehyde 3-phosphate back to RuBP, the acceptor for CO2, thereby completing the cycle. For every three molecules of CO2 that enter the cycle, the net output is one molecule of glyceraldehyde 3-phosphate (G3P). For each G3P synthesized, the cycle spends nine molecules of ATP and six molecules of NADPH2. The light reactions sustain the Calvin cycle by regenerating the ATP and NADPH2.

There is evidence that at night the plant goes into a differant state for growing thus could be called "sleep" and the dark period is needed!! Im sure the reason people consider this being asleep is because this is done ONLY at night. Now weather the plant is really sleep I guess no one will really know. But the plant is doing something different at night that slows down leaf growth, considering a plant is mostly made up of leafs and it slows down 75% of a plant is sleeping or in a dormant state of growth. So when they say sleeping, common scene tells me that if leaf growth is slowed at night then this would be sleep considering its NIGHT time.

what about in the winter when they arnt getting rained on? they also say that if there isnt enough water for a plant that wont die every year will go to sleep this shocks the plant to go dormant/sleep mode. So there is no need for water to go to sleep.
Comparing dormancy and sleep is about as retarded as you can get. Not even close to the same thing.

You and your boyfriend should look stuff up b4 you open your mouth

dor·mant (dôr
m
nt)adj.
1.
Lying asleep or as if asleep; inactive.
2. Latent but capable of being activated: "a harrowing experience which . . . lay dormant but still menacing" (Charles Jackson).
3. Temporarily quiescent: a dormant volcano. See Synonyms at inactive, latent.
4. In a condition of biological rest or inactivity characterized by cessation of growth or development and the suspension of many metabolic processes.

Now how restarted are you?

Effects of Sunlight on Photosynthesis


  • Trees don't produce food at night. Night time sky and moon image by Heather Ferrebee from Fotolia.com In a sense, trees and plants go to sleep at night just like the rest of us. Leaves take a break from photosynthesis when their stomata close at night. The stomata close with the help of surrounding guard cells that regulate the rate of transpiration (moisture release). Guard cells are turgid and swollen during the day, which allows the stomata to take in carbon dioxide. When light levels are substantially decreased during the night, guard cells go flaccid, and stomata are closed. Trees are ready to begin the cycle of photosynthesis again at daybreak.

thus could be called "sleep" must not be registering. Maybe in your second semester of environmental science they haven't covered these botany terms these Master growers, mostly Rastadred22 are using.

When you use info from a site to teach children, & other beginner sites, you find things simplified. They compare plants to humans to make kids understand. I see they taught him, he just took it to heart as the full knowledge. It's getting old explaining botany, huh, Cowboy.
