Detailed explanation-1: -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.
Detailed explanation-2: -Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. The chlorophyll pigment is responsible for the green colouration in plants.
Detailed explanation-3: -In plants, the so-called “light” reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.
Detailed explanation-4: -Chlorophyll role is to absorb light from sunlight in plants. The energy absorbed from light is utilized to convert carbon dioxide and water molecules into glucose, through photosynthesis. Chlorophyll being a primary pigment (photoreceptor) reflects green light, absorbing red and blue light in the chloroplast.
Detailed explanation-5: -Chlorophyll is a pigment found in the chloroplasts of cells. During photosynthesis, chlorophyll absorbs light from the sun and turns it into chemical energy the plant can use as food. Chlorophyll has also been used in alternative medicine and has shown to have medicinal benefits.
