- The red and violet-blue light emitted from the sun are absorbed by the chlorophyll and used to drive most of photosynthesis. The green light is not absorbed and then reflected back which gives the leaves of plants their green color, according to the Central Michigan University. Continue Reading.

Difference Between Chlorophyll A and B In chlorophyll A, the most effectively absorbing wavelengths of the spectrum are 429 nm and 659 nm, which are responsible for violet-blue and orange-red colors, respectively. Chlorophyll A reflects blue-green color, which is responsible for the green color of most of the land plants.

- Answer The formula for photosynthesis (abv. photos.) is: Light Energy + Co2 + H20 -----> Carbohydrate + Oxygen As a whole, photos. takes place in the … chloroplasts of a plant cell. There are two main reactions that occur during photos. The light-dependent reaction and the light-independent reaction.

Light Absorption for Photosynthesis It is evident from these absorption and output plots that only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis. The reflection and transmission of the middle of the spectrum gives the leaves their green visual color. Light must be absorbed for nutrients to be created by Photosynthesis.

Photosynthesis - Part I: The Sun and Light Even when light gets to a plant, the plant doesn't use all of it. It actually uses only certain colors to make photosynthesis happen. Plants mostly absorb red and blue wavelengths. When you see a color, it is actually a color that the object does NOT absorb. In the case of green plants, they do not absorb light from the green range.

The Light-Dependent and Light-Independent Reactions As you’ve probably gathered by now, the light-dependent reactions fuel the second stage of photosynthesis called the light-independent reactions. Our good buddy carbon dioxide (CO 2) provides an excellent source of carbon for making carbohydrates.

How are the colors of the aurora created? Atomic oxygen is responsible for the two main colors of green (wavelength of 557.7 nm) and red (630.0 nm). Nitrogen causes blue and deep red hues. This is the spectrum of colors emitted by the various atoms in earth’s outer atmosphere.

What Are the Two Stages of Photosynthesis Called? Quick Answer. Photosynthesis takes place in two stages: the light reactions and the dark reactions. The light reactions take their name because they require the presence of direct light, while the dark reactions do not have the same proviso.

- I am not sure what you mean by level of light, but I will answer your question in to ways - in terms of the intensity of light and wavelength of light. Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature. Light is an extremely important factor for the process.

Biological pigment The principal pigments responsible are: Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs yellow and blue wavelengths of light while reflecting green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a.

What Is the Role of ATP in a Light-Independent Reaction? The process of photosynthesis involves two main phases of reactions: the light reactions, those that require light energy, and the Calvin cycle, which is the light-independent stage. The main reaction during the light-independent reaction is the conversion of carbon dioxide into organic molecules.

Where is Chlorophyll Found in Plant Cells? Photosynthesis begins with light absorption. Chlorophyll absorbs all colors of light except for green -- plants appear green because chlorophyll reflects back the green wavelengths that strike it. This light energizes electrons inside the chlorophyll, giving the plant energy to power sugar synthesis.

Describe in general the two main stages of photosynthesis.? Events occurring during light reactions: Absorption of light energy by chlorophyll molecules. Splitting of water molecules into hydrogen and oxygen atoms. Formation of ATP and NADPH 2. Dark reaction s – This reaction does not require direct light and occurs in the stroma of chloroplasts.XPERT ANSWER. The process of photosynthesis occurs in two phases – the light reactions and the dark reactions. Light reactions – As the name suggests, this reaction takes place in the presence of light.

Photosynthesis absorbs blue and red-orange light that is missed by chlorophyll a. Chlorophyll a and b reflect light of green wavelength and therefore look green to our eye.

- White light is made up of all wavelengths (colors). Objects appear colored when they absorb or reflect different wavelengths of light to different degrees. The color that we see is the transmitted or reflected color. Chlorophyll helps to convert light energy into chemical energy by absorbing electromagnetic radiation.

Chapter 6: Photosynthesis Red (660 nm) and blue (440 nm) lights are required for the process of photosynthesis. Low rate of photosynthesis from the plant is expected if a plant is placed into an environment where only green light is received. Chlorophyll reflects green wavelength (550 nm) and absorbs the blues and the reds most.

What Kinds of Light Do Plants Grow Better In? Light consists of several colors, but plants do not need all of the colors. Red and blue are the most important colors required by plants for energy. Of the two, red light is more important. Plants that receive natural light through windows or by growing outdoors receive the proper balance of red and blue light.

Photosynthesis: How Plants Transform Energy from the Sun The Dark Reactions. The second phase of the process of photosynthesis can occur in light or darkness. Energy stored in ATP made during the first phase of photosynthesis combines with carbon from carbon dioxide, as well as hydrogen, to eventually form glucose.

What is the primary photosynthetic pigment in plants? Chlorophyll, the pigment found in plants, some algae, and some bacteria that gives them their green color and that absorbs the light necessary for photosynthesis. Chlorophyll absorbs mainly violet-blue and orange-red light.

Why is the importance of chlorophyll in plants? Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion.

- Which wavelengths of the solar spectrum drive photosynthesis? The wavelengths of sunlight between 400nm and 700nm are the wavelengths that are absorbed by chlorophyll and that drive photosynthesis. Energy Incident on a Leaf Photosynthesis is not a very efficient process. Of the sunlight reaching the surface of a leaf, approximately:

- Light and dark reactions in photosynthesis Photosynthesis is divided into two parts: 1. Light-dependent reactions (light reactions) 2. Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls.

- Red and blue light have the greatest effect on plant growth. Green light is least effective to plants as they reflect green light and absorb none. It is this reflected light that makes them appear green to us. Blue light is primarily responsible for vegetative growth or leaf growth.
