Chloroplast: meaning, definitions and examples
๐ฑ
chloroplast
[ หklษrษหplรฆst ]
cell biology
Chloroplasts are organelles found in plant cells and the cells of some algae. They are responsible for photosynthesis, a process that converts light energy into chemical energy stored in glucose. Chloroplasts contain chlorophyll, the green pigment that captures light energy. These organelles are enclosed by a double membrane and contain their own DNA, allowing them to reproduce independently within the cell. Larger plants typically have a higher number of chloroplasts per cell to maximize their ability to capture light energy.
Synonyms
green plastid, photosynthetic organelle
Examples of usage
- Chloroplasts enable plants to produce their own food.
- Without chloroplasts, plants would not be able to photosynthesize.
- The green color of leaves comes from chloroplasts.

Etymology
The term 'chloroplast' is derived from the Greek words 'chloros', meaning green, and 'plastos', meaning formed or molded. The word was first used in the late 19th century when scientists began to identify the distinct structures within plant cells that were involved in photosynthesis. Chloroplasts were recognized as specialized organelles capable of converting sunlight into chemical energy, a critical process for life on Earth. Over time, research continued to uncover the complex nature of chloroplasts, including their own genetic material and their evolutionary origins from cyanobacteria, a process known as endosymbiosis. This understanding has significantly advanced our knowledge of plant biology and ecology.
