Plant Cell Chloroplasts

What are chloroplasts?

Chloroplasts are unique structures found in plant cells that specialize in converting sunlight into energy that plants can use. This process is called photosynthesis.

Organelle

Chloroplasts are considered organelles in plant cells. Organelles are special structures in cells that perform specific functions. The main function of the chloroplast is photosynthesis.

Chloroplast Structure

Most chloroplasts are oval-shaped blobs, but they can come in all sorts of shapes such as stars, cups, and ribbons. Some chloroplasts are relatively small compared to the cell, while others may take up the majority of the space inside the cell.

Photosynthesis

Chloroplasts use photosynthesis to turn sunlight into food. The chlorophyll captures energy from light and stores it in a special molecule called ATP (which stands for adenosine triphosphate). Later, the ATP is combined with carbon dioxide and water to make sugars such as glucose that the plant can use as food.

Other Functions

Other functions of chloroplasts include fighting off diseases as part of the cell's immune system, storing energy for the cell, and making amino acids for the cell.
