if we put a candle near a plant,does it replace the sun,explain please?

Answer 1

You have the right logic, because a candle gives off a spectrum of light, just like the sun does. However, ONE candle produces such a small amount of light, compared to what a plant needs for successful photosynthesis, that it would be worthless. Plus, the sun gives off a wider spectrum of light wavelengths. Plus, the heat given off by the candle flame could burn the plant's foliage, if it was too close to the plant.

You'd have MUCH better success buying one of the special fluorescent "grow lights" sold in nurseries. They're "cool" lights and so won't burn the foliage, plus they are designed to give off light in the wavelengths best suited to plants.

Answer 2

artificial lights that have the sufficient spectrum and intensity for the plant involved can replace the sun as the energy source for a plant

many plants are grown indoors this way

i don't think there are many (maybe none) plants that would be adequately energised by a candle (limited spectrum, low intensity)

Answer 3

The idea is a correct one. People do grow plants under artificial light. That is using lamps powered by electricity as a light source replacing the sun.

Answer 4

No, it does not. The candle is not putting out the correct light wave as sunlight. It also does not do it at the same intensity that the plant needs.

Answer 5

It's rays from the sun, not heat, that plants photosynthesize. Thus flourescent lights can "replace" sunlight for plants, but candles, fireplaces, and regular light bulbs cannot.

Answer 6

the international's oldest recorded tree is a 9550 three hundred and sixty 5 days previous spruce contained in the Dalarna province of Sweden. way cool, i'm hoping they do all they could to keep it alive. i ought to like to be sure it. (love timber, uh oh, am I a Druid?) Creationists: properly some solutions have already lined what i became going to say "Heads exploding" "singing lalalalalala" and positively their fall guy devil!! some, probably are wondering (gasp) and revamping their outlook. remember in ordinary words 'God' can make a tree. ;-D I had a co worker who with the exception of transforming into completely speechless even as a fellow co worker suggested he became an Atheist, later moaned that it wasn't straightforward that many timber had longer lives than human beings. I informed him timber make contributions a procedures more suitable than human beings do to the properly-being of the planet. bypass timber!! Creationists were 'placed right here' for the leisure of something else individuals. (exploding heads and all) over a million/2 million years in the past. (surely purely reduce them open and count number their earrings!)

Answer 7

photosynthesis requires light, specifically light waves of 680nm (nano meters) and 700nm. This is the requirement that the sun provides in photosynthesis. So to answer your question, since all the sun provides is 680nm and 700nm rays of light, then if the candle produces light of these wavelenghts, and in sufficient amounts, (plus the candle does not burn the plant) , then yes, most definitely!

this would work in theory, i doubt you could pull it off experimentally

Answer 8

No it doesnt as the sun gives out ultra violet rays or light where a candle only emits light

Answer 9

No Sunlight produces chemicals that plants need to survive. Fire from a candle won't do that.

Answer 10

nope candle gives off heat and light and plant might grow twards it, but it most likely doesn't give off enough to fuel the plant for long
