its a pigment, not a cell, it is only a part of a cell.

bacteria
 

it is unicellular.....

its a pigment found in chloroplasts of plant.

hello
 

Plant cells have pigmented bodies called plastids which are of three types
Chloroplasts
Chromoplasts
Leukoplasts

Chloroplasts are meant for photosynthesis where it combine carbon dioxide and water to form glucose.
Chromoplasts are usually found in parts of the plant where we see colors like petals or vegetables.
Leukoplasts are usually found in those parts of the plant which are concerned with food storage.

Thus
Its a part of cell.
Found only in plants.
Concerned with preparation of foood through photosynthesis.

Dear your opinion is wrong. Answer to I5 is 24 hours as four minutes does not make any sense. the correct answer is 24 hours.

can you plz suggests any books

chlorophyll
 

it is not a cell rather it is an organelle in cell it also has its own nucleus thus can reproduce its self it contains magnesium ion in it and is responsible for giving green color to plant it is a type of plastids and invovled directly in photosynthesis process
