Chloroplast Function. Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis.
A cell can have different types of mitochondria (heteroplasmy) or same type of mitochondria (homoplasmy). Chloroplast DNA: Like mitochondria, chloroplast also contain circular double stranded DNA molecules. They too do not associate with histones.hloroplast DNA is a circular molecule of DNA located in chloroplasts (an organelle mostly in plant cells and other eukaryotic organisms that perform photosynthesis).
