Question

Organisms have several differing types of chlorophylls. Explain how this variation enables these organisms to have a greater fitness.

Answer 1

Answer

Chlorophyll - pigment is found in a plant’s chloroplasts, which are small structures in a plant’s cells. this is often where photosynthesis takes place absorbs principally within the blue and to a lesser extent red parts of the electromagnetic spectrum, hence its intense green color. additionally, to giving plants their green color, chlorophyll is important for photosynthesis because it helps to channel the energy of sunlight into chemical energy. With photosynthesis, chlorophyll absorbs energy and so transforms water and CO2 into oxygen and carbohydrates.

Chlorophyll occurs in many distinct forms, chlorophylls a and b are the main types found in higher plants and green algae; chlorophylls c and d are found, usually with a, in several algae; chlorophyll e is a rare type found in some golden algae, and bacterio-chlorophyll occurs in a certain bacterium. In green plants, chlorophyll occurs in membranous discoid units (thylakoids) in organelles known as chloroplasts.

Chlorophyll is found in all organisms that photosynthesize, together with an alga. the reason that chlorophyll a is crucial is that it's ready to capture light-weight wavelengths that fall within the spectrum of sunlight. Once captured by chlorophyll a (which is found in an organelle referred to as chloroplast), sunlight combines with water and CO2 to produce energy and glucose molecules used to power the alga cell's function. chlorophyll a is a green pigment, that is what offers plants and plenty of algae their natural green color.

Chlorophyll b is a green chlorophyll pigment found in plants and green algae. chlorophyll b augments chlorophyll a's ability to capture sunlight

Chlorophyll c occurs in certain types of algae, including dinoflagellates. similar to chlorophyll b, chlorophyll c helps to gather sunlight, however, it doesn't participate in photosynthesis beyond the initial stage. chlorophyll c could be a reddish-brown pigment and gives dinoflagellates its distinctive color.

These kinds of chlorophyll work in concert to allow maximum absorption of light within the blue to red spectrum; but, not all photosynthetic organisms have the chlorophyll b pigment. These chlorophyll molecules capture light energy and transfer it to the reaction center of the cell. From here, electrons are passed from this absorbed light energy to water molecules leading to the formation of hydrogen ions and oxygen. The oxygen is discharged as a by-product; whereas the hydrogen ions are transferred across the plant’s thylakoid membrane leading to the phosphorylation of adenosine diphosphate (ADP) into adenosine triphosphate (ATP). ATP then later reduces a coenzyme called nicotinamide adenine dinucleotide phosphate (NADP) to NADPH2, which is then used to convert CO2 into sugar.
