Difference between Mitochondria and Chloroplast

Mention of the two organelles, mitochondria and chloroplasts, typically bring to mind terms like ‘energy’ and ‘photosynthesis’ respectively. But what are these two organelles actually responsible for in the plant cell? And how do they differ from one another? In this post, we take a closer look at these two organelles and examine their individual functions within the plant cell.

What are Mitochondria?

Mitochondria are organelles that serve as the powerhouses of the cell. They are located in the cytoplasm of the cell, and their primary function is to produce ATP through cellular respiration. Mitochondria are unique in that they have their own independent DNA and ribosomes, which allows them to carry out their own protein synthesis. In addition, mitochondria are able to change their shape and number in response to changes in the cell’s energy needs.

What is Chloroplast?

Chloroplast is a specialized organelle found in plant cells that serves as the site of photosynthesis. Chloroplasts are small, round structures that contain a green pigment called chlorophyll, which allows them to capture energy from sunlight. Chloroplasts are essential for plants because they enable them to absorb carbon dioxide from their environment and convert it into glucose, which can then be used for growth and other processes. Chloroplasts also play an important role in respiration, helping the plant to break down sugars for energy. Overall, chloroplasts are one of the most integral components of any plant cell, and their unique properties allow plants to thrive under a wide range of environmental conditions.

Difference between Mitochondria and Chloroplast

Mitochondria and chloroplasts are two types of organelles that play essential functions within the cell. Mitochondria are often referred to as the “powerhouses” of the cell, as they help to generate energy through the oxidation of nutrients. On the other hand, chloroplasts are involved in photosynthesis, transforming energy from sunlight into chemical energy that fuels cell growth and development. Despite their similar names and overlapping functions, there are several key differences between mitochondria and chloroplasts. For one thing, mitochondria have their own genetic material, whereas chloroplasts have chromosomes that belong to the cell itself. Mitochondria also have more intricate inner membranes than chloroplasts, which contain a series of folds that serve to maximize surface area for energy production. Overall, these two organelles play important roles in different cellular processes and must be carefully maintained to ensure optimal functioning in both plant and animal cells.


The mitochondria and chloroplast are two organelles in a cell with different functions. Mitochondria produce energy for the cell while chloroplasts convert light into chemical energy that is used by plants to create glucose from carbon dioxide and water. Understanding the difference between these two organelles can help you better understand photosynthesis and cellular respiration.
