The Color Of Light Affects Plant Growth

The diagram above shows the two stages of photosynthesis. As you can see, light is a key component as it start the light-dependent reactions which produces ATP and NADPH, which is needed in the light-independent reactions to make glucose. So without light, there is no ATP and NADPH produced and thus no glucose produced, therefore the food chain cannot be started. Glucose is also needed to make DNA and hormones for plant growth, it is also require during plant respiration. So it can be established the light is vital for plant growth and it affects the height of plants indefinitely.

The green pigment involved in photosynthesis is chlorophyll. Chlorophyll is green in appearance because it absorbs red and blue light, making these colours unable to be seen. It is the reflection of the green light that reaches out eyes, giving chlorophyll a green colour. This green light that can be seen cannot be used by the plant for photosynthesis. Therefore, theoretically growth should be inhibited in the plants only exposed to green light.

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

The purpose of this experiment was to investigate the effects of light intensity on the rate of photosynthesis in a Moneywort plant. By observing the plant in distilled water mixed with sodium bicarbonate, different light bulbs were targeted onto the plant. The measurement of the amount of bubbles present on the plant during the trial of the experiment enabled us to identify the comparisons between the activity of the light and the process of photosynthesis.

Plants capture light energy and transform it into chemical energy. This chemical energy is transferred from plants to animals via the food chains.

Photosynthesis is the procedure in which green plants use sunlight, carbon dioxide and water to make food and oxygen and cellular respiration is the process where cells use this food to

4.) What conclusions can you draw about which color in the visible spectrum causes the most plant growth?

In my research paper, I will attempt to determine how the perception of light in phytochromes plays a role in the development of plants. Specifically, I will look at how phytochromes play a role in the growth and development of Arabidopsis thaliana. The paper will also look at how light perception plays a role in phototropism and the immune systems of a plant. Finally, my paper will explore how changing light conditions impact perception in phytochromes.

Based on your data, draw a conclusion regarding how light intensity affects the rate of photosynthesis.

Photosynthesis occurs in all green plants and is the beginning of nearly all food chains therefore a source of life to all living organisms. It is the process where plants transform light energy from the sun into chemical energy. By using light energy trapped by chlorophyll (light absorbing pigment), plants combine carbon dioxide and water to form glucose and oxygen.

The authors are trying to determine how elevated Tsoil and elevated CO2 will affect the physiological responses of shade-tolerant species in light conditions. Also, how elevated CO2 and high light treatment affect physiological traits of shade-tolerant plants.

For all living organisms including plants, respiration is the process of converting chemical energy into a usable form of energy (Biol 171L Lab 7). Even if an organism does not have an energy source, they will keep respiring. For autotrophic plants, the process of obtaining energy is called photosynthesis. It harvests solar energy, carbon dioxide, and water to form a usable form of energy (Tanaka 2009). The factors that go into this process includes the pigment the plant possesses, and the intensity, wavelength, and direction of the light. Plants that contain the pigment chlorophyll-a are the ones we see as the leaves of common trees, or grass.

All this lights have equally conurbation towards plants growth but without any light then there is no process of photosynthesis which means there no plant growth at all. Photosynthesis is the procedure whereby radian vitality from the sun is changed over to the concoction bond vitality of glucose. In plants it happens in chloroplasts which concentrated cells. Chlorophyll atoms are instrumental in the first step, which is the change of light vitality to the substance bond vitality of ATP. Vitality to change carbon dioxide and hydrogen to glucose is then given by the ATP. Oxygen is discharged as a waste result of procedure. The reaction is shown below:
