Chlorophyll is an important pigment in plant which supports photosynthesis in which inorganic substances are converted to organic food for self consumption and consumption of organisms of higher trophic levels. Plants play the role of producers in the food chain, without chlorophyll, photosynthesis is not possible and food cannot be consumed.
furthermore, plants through photosynthesis plays an important role in the Carbon cycle. Without chlorophyll, photosynthesis will not be possible and thus carbon in the atmosphere cannot by recycled.
Also, in photosynthesis, plants take in carbon dioxide and releases oxygen, this can help maintain the oxygen-carbon dioxide balance of the atmosphere.
Mitochondria is important in respiration in which glucose is broken down into energy, CO2 and water. Thus it is the powerhouse of the cell.
more number of mitochondria more metabolic activity
Mitochondria tend to congregate where energy is required. More energy is required in animals as they have to move around while plants need not, thus more mitochondria is present.
