What is chlorophyll?

Answer 1

Chlorophyll is a green pigment (one of several photosynthetic pigments) that plays a crucial role in producing food for green plants by synthesizing simple sugars (glucose) from carbon dioxide and water in the process of photosynthesis. The by-product of photosynthesis is free oxygen. So chlorophyll is a vital chemical in maintenance of life on Earth, providing food and oxygen for living things.

The reaction preformed by chlorophyll can be expressed as:

6CO2 + 6H20 + Sunlight => C6H12O6 (glucose) + 6O2

6 molecules of Carbon dioxide and 6 molecules of Water are converted into

1 molecule of glucose sugar and 6 molecules of oxygen.

• Chlorophyll is found in chloroplasts, an organelle found in the cells of the plant; chloroplasts are found in the green portions of the plant (leaves and stems).

• Green plants which can produce their own food are called autotrophs (or autotrophic).
• Chlorophyll is found in two different forms (chlorophyll a and chlorophyll b) which absorb slightly different wavelengths of light. Plants use the blue and red portion of the visible light spectrum and reflect green light giving plants their green color
• Interestingly, the chemical structure of Chlorophyll is almost identical to that of heamoglobin found in the blood in our bodies - the difference is that heamoglobin uses an iron (Fe) atom to carry oxygen, where as chlorophyll uses Magnesium (Mg) as an oxygen carrier.

Answer 2

Chlorophyll is the substance inside of green plants. When weather blocks the sun or it shows only partially over a long period of time, the green plant becomes a range of different colors: red, yellow, brown, orange, even sometimes gray. Chlorophyll is basically the glucose - sugar substance in plants. This is a pretty general idea of what chlorophyll is.

Answer 3

A green coloured photosynthetic pigment found in chloroplast of a plant .It is responsible for trapping solar energy

Answer 4

a green pigment in plants cells which absorbs light energy ,it is called chlorophyll.
