Plants that grow under high light intensities with a higher rate of photosynthesis are referred to as plants grown in light while plants that grow under low light intensities or dark conditions with a lower rate of photosynthesis are referred to as plants grown in the dark.
What are the differences between plants grown in darkness and those grown in light What do you think is the reason for these differences?
The light slows stem elongation through hormones that are sent down the stem from the tip of the stem. In the darkness, the hormones do not slow stem elongation. ... The seeds in the light-grown condition only partially rely upon their stored chemical energy and start to harness solar energy as their chloroplasts develop.
How are plants different in light and dark environments?
Plants usually produce oxygen during the day due to photosynthetic reactions and use oxygen at night due to respiration. Owing to their internal circadian rhythms, while it's dark, plants anticipate the coming of dawn and prepare for it on a cellular level before their chloroplasts are stimulated by light.
What is the difference between a plant growing in sunlight and shadow?
Leaves which grow in the shade (‘shade leaves') are generally larger in area but thinner than leaves which grow in full sunlight (‘sun leaves'). Sun leaves become thicker than shade leaves because they have a thicker cuticle and longer palisade cells, and sometimes several layers of palisade cells.
How does darkness affect plant growth?
In a strict sense, plants do not grow faster in the dark; they grow slower. However, plants seem to grow faster in insufficient light due to rapid cell elongation. ... In conditions of total darkness, plant cells will generally expand upward , a process called geotropism.
Why do plants in the dark grow taller than plants in the light?
The main reason for plants growing taller in the dark is that they are using up the extra energy that they've stored up throughout the day and will not require light until this has depleted . ... However, this does not mean that you can leave your plant in the dark for long periods of time to try increase its size.
Do plants need darkness to grow?
Plants do need that period of darkness for their metabolism to work properly. They are not designed to create food non-stop, and it will do them harm in the long term to put them in this sort of situation. So, yes, plants need their darkness just as much as they need their light .
How do plants grow at night?
The absence of light actually stimulates plants to grow fastest at night. Plant phytochromes detect darkness, encouraging growth hormone production, causing the plant to elongate in search of light. The same process helps plants orientate their foliage to light and helps seedlings stretch in search of light.
Can any plants grow in the dark?
The only plant that will grow in complete darkness is the mushroom , but what people really want to know is which plants will grow where there's very little light. ... Overwatering is always a problem, but plants receiving minimal light take much longer to dry out than those by sunny windows.
Do plants need complete darkness at night?

Which of the following is a difference between plants adapted to sunny and plants adapted to shady conditions?
What is the physical difference between plants that grow in the direct sunlight and those that grow in the shade? ... Shade leaves are typically larger in area, but thinner than sun leaves. Sun leaves become thicker than shade leaves because they develop longer palisade cells or an additional layer of palisade cells.
How does light affect plant growth?
Light intensity influences the manufacture of plant food, stem length, leaf color and flowering . Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.
What is the effect of darkness on photosynthesis explain?

Do plants need light and darkness?
During light reaction, the plant absorbs light and turns it into energy. ... Because dark reactions do not require the absence of light , plants will remain healthy when exposed to light 24 hours a day. There are some plants, however, that will survive but not thrive without darkness.
Why do plants grow towards light?
As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis . ... As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis.
Why do some plants grow faster than others?
Different plants grow at different rates
Growth of the plants is affected primarily by four factors: light, water, temperature and nutrients . Each plant species has its own requirements for its growing environment.
Do night Lights affect plants?
Summary: Artificial night time light from sources such as street lamps affects the growth and flowering of plants and even the number of insects that depend on those plants for food, a study confirms. ... The research shows that light pollution can impact the natural environment in complex ways that may be hard to predict.
Can plants grow in constant light?
Although different species have varying light requirements, no plant can tolerate continuous light exposure for 24 hours a day . Like nature's cycle of light and dark, plants need a daily period of darkness and rest to remain healthy.

Why do plants grow overnight?
Photosynthesis is a process whereby plants absorb sunlight to convert water and carbon dioxide into glucose. This glucose is the source of energy for plants, just like with humans. ... This means that plants are able to grow without sunlight which is why plants continue growing at night.
What does plants do at night?
Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide , which is called respiration.

Should I turn off the grow light at night?
A: In general, you should not leave grow lights on 24/7 . Plants need a light-dark cycle to develop properly. It's believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Is too much grow light bad for plants?
To put it bluntly, yes, too much light can eventually kill your plant . The light intensity can produces increasingly severe damage to your plant to the point where it dies. It can also dry out the plant to the point where it no longer has the water it needs for growth and photosynthesis.
Why do plants lose mass in the dark?
When seeds/plants grow in dark, they lose dry mass . When seeds/plants grow in light, they gain dry mass. Plants in the light are growing by incorporating carbon from CO 2 into their bodies. Plants in the dark obtain energy for functioning by oxidizing organic matter.
