my plants died because of cold temperature. what are the reasons scientifically speaking...

The cold temperature didn't allow the plant to perform its basic bodily functions.

I'm not sure, it sounds like it is cracked\nI think it may be difficult for you to regulate the temperature with the light.  It may be possible you are overheating them.  If they are still moving around then they are probably not getting too cold.  i think there is a chance they are ok.  The one that cracked probably didn't survive because its lungs were not developed enough.  Do you know how many days it has been?  I believe chicks should hatch after about 21 days.

This is too vague a question.  One really needs to know what type of plant or something to give a good answer.  Not all plants grow at the same rate anyway.  Plants at different ages do not grow the same either.

Write your own essay...but water freezes when it is cold and becomes ice which expands causing the pipes to burst, that's why they need lagging/insulating to prevent this happening.

Come on!  Dry Ice!\n\nTemperatures below -78 degrees Farenheit\n\nAnd your planet is Mars, but its water AND carbon dioxide in the polar caps....

Think about the adaptations that allow a cactus to live in a desert.  Could a piece of pondweed live there?\n\nWhy do fir trees grow where it is cold?   Could an oak live there?

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 water around an iceberg or floe becomes colder than freezing (like putting ice cubes in a drink), but won't turn to ice since it is salty.  And waters in the polar regions are down near freezing to begin with.  When the berg gets sunlight some of the surface will melt off.  When the berg finally drifts to warmer waters, it will melt until it is gone.\n\nFor an example: Take a sink and fill it with water.  Put in some rock salts and stir until dissolved.  Now put in several trays' worth of ice cubes.  Stir.  Some of the cubes will melt since the tap water was not freezing, but eventually the sink water will get to a temperature below 32 degrees F or 0 degrees C without freezing solid.  At that point the coldness of the water keeps the remaining ice cubes frozen and the ice cubes keep the water at a below freezing temp.  Eventually it will melt cause there will be heat absorption into the system raising the water temperature, but it will take awhile.

It's not the cold, it's the lack of sunlight. If you can afford it, invest in a full-spectrum lamp.

They dont!! Sorry to say it but that's why you see some animals dead :(.\nHoweverm they do know winter's comming up...it  kinna get cooler

I won't do your homework for you, but I will give you a few hints.\n\nThe first hint is that ddnight is talkin' smack. This has nothing to do with atmosoheric composition.\n\nThe second hint is that you should be looking very varefully at the relative effect of C4 and CAM utilisation on water LOSS. Underline the word 'loss".\n\n--------------------\n>>>CAM plants and C4's do better in higher temps than C3's.\n\nGenerally yes. But the question is why the plants died in that order. Begonia are tropical plants, so a temperature would not have killed it, and the pineapple is both tropical nad C4, sdo temperature effects can't be at play directly.\n\nOnly one plausible explanation remains.

Nothing.  Except have a lower water volume due to warmer water molecules converting to gas.  However, the warmer water may have an efffect on the plants you are studying.  If you water a plant with hot water it may kill the plant.

most house plants should be able to grow under those conditions...they sell speial flourescent likes that are taylored for plants but a normal one should do the trick

I think this guy is trying to grow something hydroponically and doesn't want anyone else to detect it.  Know Your Enemy.  At any rate, since there is so much water, there probably will be an increase in vegetation around the object in question.  As far as the difference in temperature, since water is a great heat sink, the water would probably end up being about the same temperature as the surrounding soil.  When you get more than 3 ft deep (Except in possibly extreme climates) the soil temperature stays about the same year round.  The sun just can't warm and the air just can't cool the soil fast enough for the underlying substrates to be affected.  This is why when utilities (gas, electric, water, etc) are buried, there is a minimum depth for the conduit to be below the ground so that changes in temperature will not affect the performance and/or integrity of the circuit, in addition to the fact that the average guy can't just come along with a shovel and damage it.  One thing that may affect the temperature of the buried object is how well the soil it was buried in was placed around the object (i.e. the density of the soil placed).  If the area was just backfilled with no attempt to pack the soil, the soil would have large pockets of air in it which would allow it to not only retain the heat it has, but also settle relative to the surrounding natural soil.\n\nI hope this helps.

temporarily it will be cold and if you have sensitive skin it can itch and turn red since salt makes the temperature go wayyy down, long term is bad because the tmeperatures can get to the negative dgrees, you can definitely get frostbite

They can't know, just like we can't.  \n\nThey may be able to read cues and clues like we do, but they are not prognosticators.  \n\nGenerally plants and animals are adapted to the area they live in, and know how to prepare either from experience or even genetic cues.  Also, they always seem to prepare for the worst.  I've seen trees in warm California lose there leaves because they thought winter was coming.  It was, but they could have easily grown through the mild winter.  They were a species adapted to a different climate.\n\nGood question.  It shows you're thinking about your world!

It stops plant growth, meaning at times like winter, a plant has to stop growth, conserving its energy and making it more useful at a better time like spring. (Give me best answer :))
