Chloroplasts
The chloroplasts are a type of cromoplastos that are located in the photosynthetic plant cells and the algae green.
They can be moved by amoeboid and contractile movements, and are placed in the part of the cell that receives the greatest amount of light. Photosynthetic algae usually have one large chloroplast, but plant cells have a few dozen.
The internal environment of the chloroplast is called the stroma, and it is composed of a solution of carbohydrates, lipids, protides, nucleic acids, pigments, nucleotides, salts and elements.
Its main function is to capture light energy and use it in the synthesis of organic matter.
