Difference Between Chlorophyll and Chloroplast

The difference between chlorophyll and chloroplast is due to the following factors like location and involvement in photosynthesis. Existence: Chlorophylls exist as the primary photosynthetic pigments inside the chloroplast. Conversely, chloroplasts exist as the photosynthetic cell organelles in a plant cell and possess a membranous structure that resembles mitochondria. Involvement in photosynthesis: Chlorophyll mainly absorbs …
