According to endosymbiotic theory, chloroplasts are believed to have a prokaryotic origin. The DNA present in the chloroplast is circular and the ribosome (the 70S) is similar to the one found in bacteria. The nucleus is also absent in a chloroplast.

WebIntrons can be removed by three mechanisms: 1) the nuclear spliceosome, 2) self-excision, or 3) maturase enzymes. MatK is the only maturase encoded in the chloroplast of plants. Maturases are prokaryotic enzymes that bind and excise a single intron. MatK interacts with seven different introns instead of the single intron of prokaryotic maturases. WebThe chloroplast's job is to carry out a process called photosynthesis. In photosynthesis, light energy is collected and used to build sugars from carbon dioxide. The sugars produced in photosynthesis may be used by the plant cell, or may be consumed by animals that eat the plant, such as humans.
