passion flower(how is it affected by the day-and-night cycle?)?

The flower opens during the day and closes during the night.

Good suggestions here already, but perhaps I could add:\n\nHerbs:  passionflower, hops, camomile, baical skullcap, oatstraw, motherwort.  This last plant is known for its nurturing effect, although in Florida might be hard to find.  Its Latin name is leonurus cardiaca, so its slight beneficial effect on blood pressure and on heart palpitations has been known since ancient times.\n\nI'll add valerian with a special note:  it's generally used for insomnia or anxiety, but it has a counter-effect with a small minority of people - it speeds them up instead of calming them.  So if you try valerian I'd try it alone, not in any combination, so you can determine whether you belong to the majority or the minority group.\n\nTo nourish the adrenal glands, which in turn will permit one to tolerate stress better:  oatstraw and nettles.  Nettles as in stinging nettles.  One of the most beneficial herbs in the plant kingdom.  Contrary to its common name, plant has a slightly sweet flavour.  Chock full of vitamins & minerals, more than spinach or broccoli.\n\nOne can usually find combinations of these herbs in tea preparations or in tincture form.  If you get to Washington state you can probably find wild nettles growing in the countryside, or someone who knows how to find & harvest them.  Make nettle soup, as north Europeans did for centuries in the spring - it perked them up after long winters without fresh veggies.\n\nFlower essences:  in addition to Rescue Remedy, there's also mustard flower essence (for grief) and bleeding heart flower essence (mourning something that's lost).\n\nWould you have time to try yoga?  Or even just to read Yoga Journal in a library, it's inspiring to read about people practising yoga to grow their minds and spirits as well as their bodies.

Some is radiated back into space at night, some is transformed into mechanical energy (rain, clouds, winds) and some is transformed into plant matter by photosynthesis.

The Passion Flower is quite nice.  Orchids are pretty too.

you cant tell sex till light changes ..or you till\nchange light artificially.They wont get pollinated unless you plant them near pollinating marujuana male which chances are low in the wild.Just put them outside and pluck those males as they appear

>>>>What happens with the pollen from Flower A\n\nNothing much. Any that gets scraped off will almost certainly die. This isn't really any different from what would happen if you placed horse semen inside a dog. The pollen has alimited lifespan after which it dies, and it can't fertilise anything before then, so it simply dies.\n\n\n\n>>>>Since I'm assuming it can't pollinate Flower B with it\n>>>>or can it?\n\n\nIt would be very unlikely. As other have mentiond cross pollination does occur occassionally, but 99.99999% of the time it would simply die. You can't pollinate an oak flower with clover pollen under any cicrcumstances.

Plants can sustain photosynthesis (and release oxygen) from any lightsource that has enough energy. But plants can also get stressed by too much light and actually get sick. They might also grow in unnatural ways, like growing sprouts all over, if "fed" the wrong amount of light for too long periods of time. \n\nPlants are tuned to natural light during ordinary hours but some plants can even "OD" on sunlight. When the sun shines too hot during a hot day they sometimes shutdown photosynthesis and begin to perspire. \n\nIt all comes down to what kind of plant it is. An ordinary house plant should release oxygen if the artificial light is not too intensive.

The Daylilly only blooms for one day. but there is a cactus that has a flower that only blooms a few minutes before it welts and dies, sorry don´t know the name

as the name goes...sunflower will bend towards sunlight and carries same way thorught day until sun sets. at this time sunflower's face is in east dierction. there are pictures over internet but they are still and hence wont be able to understand better.\n\nSunflower contains photovoltaic cells which make them to track sun.

Could be a lot of things. What do the flowers and leaves look like? Or can you ask your friend, maybe?\nCould be a forsythia, a kerria, a broom, a flanelbush, an oregongrape, a hypericum, or a rose. Or a lot of other things. Hopefully it's a flanelbush (fremontodendron).

At noon, one of my closest friends is getting married!  She is a sun-lover, so it'll be an appropriate day for her.\n\nAny other ritual/celebration depends on my significant other... if she's up for a ritual, we'll have one (indoors, unfortunately... no "comfortable" area outdoors for us to do anything "formal")... otherwise, I will just do a little meditation in my room before bed and most likely read aloud the Summer Solstice passages from DJConway's Celtic Magic.\n\nBright Blessings!

Plants undergo photosynthesis i.e. in absence of light, they inhale oxygen and exhale carbon dioxide.  In presence of light, the process is reversed.\n\nAssuming that you are experimenting with a plant (& not a farm).  You can pump fresh air in a chamber and keep the plant dark, you will see some improvemnets.  However you will see loss of chlorophile (which makes the leaf green) and eventually leaves will become brown...Hence, you do need a light/dark cycle.\n\nSo provide light/dark cycle and during light cycle, provide ample carbon dioxine and in the dark, increase air circulation and plant will grow like a weed.

I remember a girl in the news who ended up inhaling a piece of the X'nas tree and ended up getting a horrid asthma attack.  For years she lived with it until she was operated on about 10 years later.  After extracting the snall twig the leaf parts still had chlorophyll in it.

Spring or fall...at dusk--right when the stars are starting to come, but still light.  You would hear water somewhere enarby and the tree's would sway with a light breeze.  Candelight, a dance floor, romantic music and  your true love at your side. Bright flowers everywhere...laughter, a beautiful cake. Swaying to the mi=suic in the beautiful white gown as you hold onto your man, hoping that  moment will never end.

You will need to reschedule your time. If you really like the flower design you have to make time for it,just like you make time for eating and sleeping.Give priority to your studies.Only you can do it.

What temperature graphs are you looking at?\n\nhttp://www.rap.ucar.edu/weather/upper/crp.gif\nhttp://en.wikipedia.org/wiki/Image:Co2-temperature-plot.svg\n\nNot exactly sinusoidal. Probably the answer to you question is just the diurnal cycle of warming during the day and cooling during the night, but you won't get any good answers unless your question is more specific.

Perhaps you are thinking of a general term, like phototropism ... meaning movement towards light. This is the phenomenon shown by sunflowers turning towards the sun. Some of the insectivorous plants that others mentioned, like Sarracenia, Nepenthes and Cephalotus don't actually move but catch their prey passively by luring them into their 'pitchers'. Fly Traps move, Drosera moves (v-e-r-y slowly) and Utricularia moves to trap the small critters in the little bladders. One plant that no-one has mentioned is the sensitive plant -- the second link shows it in action (response to a flame but touch will do it) and gives this movement the jaw-breaking name thigmonasty!!
