The leaf. Unlike animals, plants do not have specialised excretory organs. Excess carbon dioxide and oxygen are excreted from the plant through the stomata in the leaves.

The function of the sodium bicarbonate in this experiment, was providing carbon dioxide for photosynthesis to occur. Light independent reactions take part in the stroma. For photosynthesis to happen for a light independent reaction, carbon dioxide needs to enter the plant.

If more baking soda is added to the sodium bicarbonate solution, then the leaf disks will rise to the surface of the solution quicker because of the subsequent increase in carbon dioxide levels which induces photosynthesis in the presence of light and leads to the accumulation of oxygen in the air spaces of the spongy …

Why was sodium bicarbonate added to the solution? The bicarbonate ion acts as a carbon source for photosynthesis.

The leaf disks intake carbon dioxide from a baking soda solution and sink to the bottom of a cup of water. When exposed to light, the disks use carbon dioxide and water to produce oxygen and glucose. Oxygen released from the leaves forms tiny bubbles that cause the leaves to float.

White light

From the data collected, it can be concluded that spinach leaves absorb red and blue light the best, showing that photosynthesis occurs at a faster rate when red or blue light is present compared to when green light was present.

Colors. Chlorophyll mainly absorbs violet, blue and red light, reflecting lighter blue, green and yellow light. Carotenoids absorb much of the light blue and green light, reflecting lighter green, yellow, orange and red light.

Clear light increased the rate of photosynthesis the most, as was expected. Out of the colored lights, blue had the shortest wavelength and the fastest rate of photosynthesis. Green had only one disc rise which proves the prediction because green light did photosynthesize but very little.

white light

red light

In the absorption spectrum, it can be shown that red light and blue light are absorbed the most whereas the green light is most commonly reflected. Therefore minimum photosynthesis takes place in green light.

blue

Different pigments absorb different wavelengths of light. The leaves of a plant are green because the chlorophyll within them absorb all other wavelengths of light and reflects green light….Effect of Light Colour on the Rate of Photosynthesis.

Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum. They’re excellent for seedlings as well as houseplants, culinary herbs and other plants.

the plants can benefit from the part of orange light that near the red light . orange light help the process of photosynthesis on the account of a portion of chlorophyll B has a affinity for this light .

The hypothesis was that if a plant grew under a green light, then it would grow faster than plants under other lights. The plant that grew the fastest was the plant under the red light. The results of this experiment show a slight preference for growth for the red light followed by white or blue and then green light.

ANSWER: 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.

Researchers can successfully grow plants using only artificial light in growth chambers. But sunlight is best for most plants. It’s generally more intense than artificial light, and it’s pretty equally distributed among the different wavelengths that earthly plants have evolved to like best.

The plants will grow best under the red and blue light, as the hypothesis predicted. The green light will hinder plant growth as plants naturally reflect green wavelengths of light and therefore, the plants absorb absolutely no light.

The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.

Plants need mostly red and blue light for photosynthesis. White light, like sunlight, contains large amounts of red and blue wavelengths. But it also contains large amounts of green, yellow and every other color. Because plants absorb primarily red and blue light, those other colors go mostly unused.

Light directly influences plant growth and flowering by inducing photosynthesis and feeding plants energy. Plants are dependent on light to generate food, induce the growing cycle and allow for healthy development.

Light plays a very prominent role in the life of plants. It is important for the process of photosynthesis needs to produce carbohydrates, this carbohydrate used in respiration to several functions of plant-like growth, movement and it also controls the distribution of various plant hormones.

You can read about the light spectrum and photosynthesis. Natural light from the sun, of course, contains these wavelengths, so you expect—all other factors being equal—that plants would grow very efficiently in natural light. More intensity means more energy transferred to the plant.

So, to answer the question, yes you can use a regular light bulb to help plants grow. Your best bet would be to place a few LED lights designed for plants near your plants that need a little extra light. Be sure not to overheat the plant or to give it too much sun.

We could say that the two most important light colors to place in an LED lamp are: red and blue. Red is the main component that plants need for photosynthesis and stem elongation inhibition. Additionally, it signals to the plants that there are no other plants above it and that it can thus have uninhibited development.
