Difference Between Chlorophyll and chloroplast

Chlorophyll and chloroplast are two fundamental elements in the process of photosynthesis. Chlorophyll is the pigment that captures sunlight, the Chloroplast is the cellular organelle where the biochemical reactions of this process take place. Although closely related, there are key differences between them. In this article, we will thoroughly explore these differences and understand their importance in plant life.

Difference Between Chlorophyll and chloroplast

Difference Between Chlorophyll and chloroplast:


Chlorophyll is a photosynthetic pigment found in the chloroplasts of plant cells and other photosynthetic organisms, such as algae and some bacteria.

It is responsible for capturing the light energy necessary to carry out photosynthesis. Chlorophyll has a unique chemical structure, based on a porphyrin ring, which gives it its characteristic green color.

Essentially, chlorophyll converts light energy into chemical energy, which is used to synthesize organic compounds.


The chloroplast, on the other hand, is a cellular organelle present in plant and algae cells. It is a specialized structure, surrounded by a double membrane, where photosynthesis takes place.

Chloroplasts contain chlorophyll and other photosynthetic pigments, as well as enzymes necessary for chemical reactions that transform light energy into chemical energy.

In addition to photosynthesis, chloroplasts are also involved in other cellular functions, such as the synthesis of lipids and amino acids.


Chlorophyll and chloroplast play complementary roles in photosynthesis, a crucial process for oxygen production and energy generation in the biosphere.

While chlorophyll is the pigment that captures light energy, the chloroplast is the place where biochemical reactions occur that convert this energy into usable chemical energy.

In summary, chlorophyll is a photosynthetic pigment contained in the chloroplast, which in turn is a cellular organelle responsible for carrying out photosynthesis. Both work together to ensure the flow of energy and nutrients in photosynthetic organisms, supporting life on our planet.

FAQ’S About Chlorophyll And Chloroplast:

Are chlorophyll and chloroplast the same thing?

No, they are not the same. Chlorophyll is a pigment, while chloroplast is an organelle. Chlorophyll is present inside chloroplasts, along with other components necessary for photosynthesis.

What is the function of chlorophyll?

Chlorophyll’s primary function is to absorb light energy during photosynthesis. It captures sunlight and uses this energy to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct.

What is the function of chloroplast?

The main function of chloroplasts is to house the photosynthetic machinery. They contain chlorophyll and other pigments that facilitate the conversion of light energy into chemical energy, leading to the synthesis of carbohydrates.

How many types of chlorophyll are there?

There are several types of chlorophyll, but the most common ones are chlorophyll-a and chlorophyll-b. Chlorophyll-a is essential for photosynthesis, while chlorophyll-b assists in capturing additional light wavelengths.

Where is chlorophyll located?

Chlorophyll is located within the thylakoid membranes of chloroplasts. These membranes are arranged in stacks called grana, and they contain the pigments needed for light absorption.

Where are chloroplasts found?

Chloroplasts are found in the cells of plants and some types of algae. They are particularly abundant in the cells of leaves, where photosynthesis predominantly occurs.

Do all plant cells have chloroplasts?

No, not all plant cells have chloroplasts. While most plant cells, especially those in the leaves, contain chloroplasts, certain cells in roots, stems, and other non-photosynthetic tissues may lack chloroplasts.

Can animals have chloroplasts?

Generally, animals do not have chloroplasts. However, there are some exceptions, such as certain sea slugs that can incorporate chloroplasts from the algae they consume and use them for photosynthesis.
