How are plants grown in the light different from the plants grown in the dark?

As long as you stick to your original plan then it will be a fair test.
If the idea is to keep one set of seeds under a mug (in the dark) and another in sunlight then make sure you give them the same amount of water each and so on. But if your test is to give one water and one not then only change that and nothing else. The same applies to any other test you wish to do.

In low light conditions a number of plants will exhibit minor adaptations to the poor environment in order to try and survive.
They will twist their stems towards the strongest source of light and try to grow towards this.
They will develop (if they have sufficient energy reserves) larger or borader leaves in order to compensate for the lower levels of light. This can be seen on some indoor plants where the source of the light is from above (and not the side), the leaves at the base of the plant now receive less light than those above; they increase in size (also sometimes darkening in colour) as they complete with the leaves above them for light.
The plant will etiolate, in other words stretch - again trying to move as quickly as possible towards the light source. This causes very noticeable lengthening of the area between the nodes - a sure sign that the plant is not receiving enough light.
These transformations do not happen within hours or days, but over a period of weeks. If a plant is placed in absolute darkness (in unregulated conditions) it can die within a week. Plants placed in cold storage (e.g. plants that are being exported via sea freight from one country to another) can survive with few ill effects for up to a month; here the temperature is lowered to between 5 and 10 degrees Celsius this slows the metabolism of the plant and so that it can survive without light for a longer period.

Why do different soil compositions favor the growth of different plants?
All soil compositions affect the growth rates of plants. Plants grown in sandy or light colored soil will grow very slowly, or may not grow at all. Plants grown in dark brown or black soil will grow the fastest and be more healthy than a plant grown in average or sandy soil.
Do plants need more light or dark?
light = photosynthesis !
Does photosynthesis have to happen in the dark?
Plants need photons in order to photosynthesize. There are photons which we cannot see, such as UV rays, but most plant energy comes from light which we can see. Also, remember that different plants absorb different kinds of light.
What do you conclude about plants in the dark?
Most plants GROW the same in dark just like in light but when it comes to food and flowering the plant will need sunlight
Photosynthiesis effect on the growth of plants in light or dark?
photosynthesis is the process by which plants harness the suns light to produce energy so they can grow.

What are etioplasts and what do they contain?
Etioplasts are chloroplast that have not been exposed to light. They are usually found in flowering plants (Angiosperms) grown in the dark.
Would it still grow even though it is in the dark?
If you are talking about plants, then no, it would not grow in the dark. It would need sunlight. Most plants grown in the dark.
Do plants need more light or dark?

What is the response of plants to periods of light and dark?
photoperiodism
List two ways that a sunflower that is grown in the dark differs from a sunflower grown in the light?
The height of the plant and the color of the leafs.
Do plants grow in light or dark better?
The process of photosynthesis depends on light. Water, carbon dioxide and light are needed for plants to grow.
Explain why plants are able to continue the dark reactions when they are not able to use the light reactions?

Do plants grow best in the dark or in the light?
Seeds and bulbs sometimes requires to be kept in the dark, but plants always need sunlight
How are the dark reactions that occur in plants dependent on the light-reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
