Quick Answer: Which Color Red Blue Or Green Will Have The Greatest Effect On The Amount Of Lettuce Growth?

What are the bubbles really showing?

How do you know.

The light increased in the beginning (0-20 light intensity), but began to stay the same the higher the temperature got (around 25 light intensity) C) What are the bubbles really showing.

The bubbles show the rate of photosynthesis by counting the amount of oxygen released (the bubbles)..

Why does blue light speed up photosynthesis?

Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn’t fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

What color should my LED lights be at night?

The answer is RED! How unexpected it is! Based on Hamsters research, red color light is the most conducive to sleep. At night red color light can significantly reduce people’s depressive symptoms compared with blue/white color light.

Does Blue Light help plants grow?

Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis. … Generally, blue light suppresses extension growth; plants grown with blue light are usually shorter and have smaller, thicker and darker green leaves compared to plants grown without blue light (Figure 1).

Why do plants grow better in some colors of light than others?

Purple and violet lights have short wavelengths and thus lots of energy. … Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll. Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth.

Will any LED light work as a grow light?

The most popular types of light bulbs to use as grow lights are incandescent or fluorescent bulbs, but you can also use LED lights, halogen lights and traditional horticultural grow lights, like high-pressure sodium bulbs (HPS) and metal-halide bulbs (MH).

Which color causes the most plant growth?

blueAs it turns out, blue appears to be the color that had the most plant growth in both experiments. Green was the lowest in both experiments, of course. Red was the second highest, violet was the third highest, and orange was the second lowest in both experiments.

What color of light causes the least plant growth?

greenThe results show that blue light contributes to the most plant growth, while green is the least. Given that white light contains all the colors of the spectrum, make a prediction what you would expect would happen to plant growth under white light conditions.

What color causes least plant growth?

greenIf red and blue are absorbed more by the plant then red and blue will be the most effective and green will cause the least plant growth.

Do plants grow under white light?

The truth is that white light works great to grow plants. The sun provides white light, after all. Red and blue wavelengths are the most important for photosynthesis, but plants use all wavelengths of light. And white light provides all wavelengths.

Which color red blue or green will have the greatest effect on the amount of lettuce growth state and explain your prediction here?

According to the experiment, Red light and blue light were absorbed by the pigment in the lettuce (chlorophyll). On the other hand, the green light was reflected by the chlorophyll pigment. The experiment . supports the prediction that the size of the lettuce would be greatest under the blue light.

Which color light is best for plant growth?

Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.

Why do plants absorb red and blue light the best?

BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth. Blue light has a wavelength that is shorter in the visible spectrum as compared to red light and has a higher energy.

What if plants were blue?

Blue would actually be a better colour for terrestrial plants to be than green, if there was a photosynthetic pigment that colour that approached that of chlorophyll in efficiency, as the sun’s peak light output is in the green part of the spectrum, and a blue pigment would not reflect as much as a green pigment would.

Why does the color blue cause the most plant growth?

Most types of chlorophyll can use the blue spectrum of light more efficiently than the red and far red spectrums of light. More of the blue end causes the cells to be elongated, changing the growth pattern of the overall plant to a more compact size with the nodes closer together.

Is red light good for plant growth?

Red light is responsible for making plants flower and produce fruit. It’s also essential to a plant’s early life for seed germination, root growth, and bulb development.

How does red light affect plant growth?

Many plants grown under only red light, such as plants grown indoors under only red LEDs, have a stretched, elongated appearance; the leaves are thin and large and plants become tall. … However, when a relatively small amount of blue light is added to red light, extension growth of plants is inhibited.

Is blue light good for aquarium plants at night?

Blue lights do not hurt plants, they are called “moonlights”.
