What is the difference between bacteriochlorophyll and chlorophyll?

Bacteriochlorophyll is a photosynthetic pigment found in prokaryotic photosynthetic bacteria or phototrophic bacteria. In contrast, chlorophyll is a photosynthetic pigment found in plants, algae and cyanobacteria. On the other hand, chlorophylls participate in oxygenic photosynthesis and produce oxygen.

What spectrum does chlorophyll absorb?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.

What do you think the purpose of chlorophyll and bacteriochlorophyll are?

They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria. Organisms that contain bacteriochlorophyll conduct photosynthesis to sustain their energy requirements, but do not produce oxygen as a byproduct. They use wavelengths of light not absorbed by plants or Cyanobacteria.

Which wavelength is best for chlorophyll a?

All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color. This wavelength is strong in natural sunlight, and somewhat present in incandescent lights, but is very weak in traditional fluorescent lights.

What is the chlorophyll used for?

Chlorophyll is the substance that gives plants their green color. It helps plants absorb energy and get their nutrients from sunlight during the biological process known as photosynthesis. Chlorophyll is found in many green vegetables, and some people also take it as a health supplement or apply it topically.

How many types of chlorophyll are there?

There are four types of chlorophyll: chlorophyll a, found in all higher plants, algae and cyanobacteria; chlorophyll b, found in higher plants and green algae; chlorophyll c, found in diatoms, dinoflagellates and brown algae; and chlorophyll d, found only in red algae.

What are the 4 types of chlorophyll?

What is the function of chlorophyll?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

What color is chlorophyll a and b?

Chlorophyll a absorbs light in the blue-violet region, chlorophyll b absorbs red-blue light, and both a and b reflect green light (which is why chlorophyll appears green).
