Detailed explanation-1: -There are many different types of pigments in nature, but chlorophyll is unique in its ability to enable plants to absorb the energy they need to build tissues. Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

Detailed explanation-2: -They also contain other pigments such as chlorophyll b and the carotenoids.

Detailed explanation-3: -There are two distinct regions present inside the chloroplasts. One is grana and the other is stroma. Grana is made up of stacks of disc-shaped structures known as thylakoids. These contain the chlorophyll molecule.

Detailed explanation-4: -Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate.
