2020-12-21 20:41 Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis,they are not only essential for the life of plants but for all life on Earth. Chloroplasts, like mitochondria, contain their own DNA, comprising approximately 130 genes, which are involved in photosynthesis and other important metabolic processes. Chloroplast genomes display considerable variation both within and between species, providing insights into the phylogeny and evolutionary adaption. Chloroplasts also carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants.
