how does plants grow better in sunlight or artificial light?

sunlight has full spectrum whereas artificial light is limited depending on what kind of bulb you use.

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.

jgardn said "The vertical growth of plants is actually stimulated by sunlight."\n\nThe vertical growth of plants is due entirely to the effects of gravity. You can demonstrate this yourself in a number of ways. The simplest is just to take some bean seeds and germinate them in the dark. No matter how often you turn them they will always turn upwards, depsite having no light at all. You can then place the seedlings in a box with alight source beneath them or beside them. Athough the seedlings will grow somwhat towards the light they will continue to grow primarily upwards.\n\n\nPlants will grow towards light, but that is not what determines vertical growth.

more plant cells.  photosynthesis (production of energy)+water+soil nutrients=plant cell reproduction and growth.

depends on the lighting. Auxin plays a huge role in the plant and can change constantly. Cytokins and Gibberellians are also horomones in a plant but they usually regulated by either the plant gene or the plant cell.

It's a tissue that grows, and it makes the plant bigger.

Sunlight is necessary for plants to grow, and to provide energy to warm the earth's atmosphere. Light intensity controls plant growth. Light duration affects plant flowering and animal/insect habits.\n\nNow, during photosynthesis, sunlight energy is used to power chemical reactions that combine water with the air's carbon dioxide to form starchy carbohydrate. In other words, during photosynthesis, sunlight energy is stored in carbohydrate for later use. Here's the simplified chemical formula for photosynthesis:\n\n6CO2 + 12H2O + sunlight ---> 6O 2 + C6 H12O 6 + 6H2 O\nor...\ncarbon dioxide + water + sunlight ---> \noxygen + carbohydrate + water \n \n\nSome carbohydrate remains in the leaf but mostly it's transported elsewhere in the plant, perhaps into the stem, or maybe into special underground storage areas, such as the potato plant's potatoes.

Depends on the plant. Some plants grow faster than others.

yes, any light can.  photosynthesis just requires photons of light at certain wavelengths, and any white light whether 'natural' or 'artificial' contains all wavelengths of light, and so photons of the proper wavelength will reach the plant and allow photosynthesis to occur.  there is nothing special about the photons from sunlight.  if i remember correctly, the wavelength plants need is 680nm for photosystem I and 700nm for photosystemII(or maybe i have that backwards) in the light cycle of photosynthesis... well anyway, you should be fine with any kind of light as long as it's not purely green light(because chlorophyll can not absorb green light, it reflects green light which is why it is green and leaves without pigmentation are green.)

what exactly is your question? \nYour potato is growing in the dark because it is what potatoes do if you give them time and water/moisture. If potatoes wouldn't do that there wouldn't be any potatoes around, they would have long ago gone extinct. \nIt is albino because light is needed to induce the syntesis of chlorophyll. It will also grow taller and only have tiny leaf-like structures because under normal circumstances a growing potato experiences permanent darkness is under the ground in the soil. It's only way to develop into a normal potato plant is grow like crazy upwards so it gets out of the ground and gets some sunlight. It is pointless to put energy at this stage in developing leaves. \nIf you never give it light it will grow until all the energy stored in the potato is used up and then it dies.

many plants tend to be healtheir and grow faster and produce more using hydroponic means.\n\nHowever not all plants can be adapted to such means.\n\nSee the sources below for more information.

Fascinating question. I would guess that under some conditions, then YES.\n\nMainly the closer to UV (bluer light) I would say could promote ripening and it would be the most like sunlight.\n\nripening of course being en-route to decay....

Because light is needed for photosynthesis which makes energy..since the seeds have no leaves and hence no photosyntheisis they get around by having enough energy material provided within the seed to allow for growth until plant is above ground and has the leaves needed for photosynthesis

The sky is beautiful, but clouds are just water vapors. How does a tree grow? Photosynthesis. Knowing how something occurs does make it less beautiful does it?

Plants use a very small portion of the light generated by a standard incandescent bulb.  They sell grow lamps which generate a wider spectrum of light that plants can use.

Trees are phototrophs, they produce their own food by using carbon dioxide, water, and sunlight.

I believe that actually the leaves of plants in the shade are more pale then in the sunlight, not darker. That's because the chlorophil which contained in leaves are not fully used for photosynthesis. The less of usage, the more pale the leaves would be. Probably u know that the leaves look greener if they have enough sunlight.
