How Does Light Color Affect Photosynthesis Essay

Lighting is in this form of electromagnetic force that travels in motion form. This variety of electromagnetic radiation is called the emission range, a tiny piece of which is visible light. Obvious light is bright that is observed by the naked human heart. Apparent light has the distance that ranges from 400-700 nanometres. The proportion of lighting absorbed by plants at photosynthesis differs for the color of the lighting. Red and purple light exist on different ends on the obvious light spectrum. Red light gets the longest wavelength of 700nm whereas purple light gets the less distance of 400nm. Red light also possesses the lesser rate while purple light possesses the higher rate. White lighting is the combination of all seven colors of the spectrum. As visible light passes through the prism that light is refracted, each bright refracting in different points. Colored lighting refracts the least whilst purple lighting refracts the most.

In the research, we can see the increase of sodium bicarbonate in the light response of photosynthesis. This can be carried out using three other coloured filters to determine the effect on the bright response of photosynthesis. Since, photosynthesis is the process whereby light life is seized by organism, algal, or bacterial cells and is used to combine essential particles from CO2 and food.

Without light plants can not photosynthesis, they have to rely on the starch the plant may have stored on previous occasions if no light is present. Therefore plants need light to photosynthesis. Photosynthesis does not occur on all parts of the leaf, but only the parts with chlorophyll (the green sections). The differences in colour on the leaf are caused by adaptations made by the plant. The parts of the leaf that are primarily exposed to sunlight contain much more chlorophyll and are the dark green patches. This makes the plant more efficient at photosynthesis by only placing the chlorophyll pigments where the sun¡¦s rays will reach it.

Plants use light energy to start the photosynthesis process and fuel the storage of energy in sugars. Light is divided into various colors with their characteristic wavelengths with each wavelength represented by an individual pigment. Chlorophyll, a specific plant pigment, takes in blue and red light while carotenoid, another type of plant pigment, utilizes blue-green light waves. Green wavelengths are not absorbed efficiently by plants and is reflected by the plant's leaves and stems, which makes plants appear green.

Background: The relationship between light and plant growth can be demonstrated by exposing leaves to various colors of light. Light supplies the power to carry on photosynthesis, the food-making process in leaves. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow. For example, leaves appear green because green is the color most leaves reflect rather than absorb and use.

Photosynthesis is the process that green plants use to convert light into chemical energy, in the form of energy-rich sugars, required for growth. The green color in plants results from a chemical known as chlorophyll. Chlorophyll absorbs the blue and red portions of the light spectrum but reflects green light, making most plants appear green. Photosynthesis consumes carbon dioxide as part of the photosynthetic process, emitting oxygen as a byproduct.
