they are both thought to originate from an endosymbiotic relationship. Evidence that mitochondria and plastids arose from ancient endosymbiosis of bacteria is as follows: New mitochondria and plastids are formed only through a process similar to binary fission. In some algae, such as Euglena, the plastids can be destroyed by certain chemicals or prolonged absence of light without otherwise affecting the cell. In such a case, the plastids will not regenerate. They are surrounded by two or more membranes, and the innermost of these shows differences in composition from the other membranes of the cell. The composition is like that of a prokaryotic cell membrane. Both mitochondria and plastids contain DNA that is different from that of the cell nucleus and that is similar to that of bacteria (in being circular in shape and in its size). DNA sequence analysis and phylogenetic estimates suggests that nuclear DNA contains genes that probably came from plastids. These organelles' ribosomes are like those found in bacteria (70s). Proteins of organelle origin, like those of bacteria, use N-formylmethionine as the initiating amino acid. Much of the internal structure and biochemistry of plastids, for instance the presence of thylakoids and particular chlorophylls, is very similar to that of cyanobacteria. Phylogenetic estimates constructed with bacteria, plastids, and eukaryotic genomes also suggest that plastids are most closely related to cyanobacteria. Mitochondria have several enzymes and transport systems similar to those of prokaryotes. Some proteins encoded in the nucleus are transported to the organelle, and both mitochondria and plastids have small genomes compared to bacteria. This is consistent with an increased dependence on the eukaryotic host after forming an endosymbiosis. Most genes on the organellar genomes have been lost or moved to the nucleus. Most genes needed for mitochondrial and plastid function are located in the nucleus. Many originate from the bacterial endosymbiont. Plastids are present in very different groups of protists, some of which are closely related to forms lacking plastids. This suggests that if chloroplasts originated de novo, they did so multiple times, in which case their close similarity to each other is difficult to explain. Many of these protists contain "secondary" plastids that have been acquired from other plastid-containing eukaryotes, not from cyanobacteria directly. Among the eukaryotes that acquired their plastids directly from bacteria (known as Primoplantae), the glaucophyte algae have chloroplasts that strongly resemble cyanobacteria. In particular, they have a peptidoglycan cell wall between their two membranes. Mitochondria and plastids are about the same size as bacteria.

Answer 6

Similarities: They are both rod-shaped, both are the main power sources of the organisms, both have their own ribosomes and DNA, both have double-membrane, and both are organelles!

Answer 7

they both are the main powersource of the organism.
mitochondria producing ATP through the kreb cycle and choroloplast uses photosynthesis do produce glucose

I looked up this site, and it appears to be very helpful. ^_^

It's a chart that directly compares mitochondria and chloroplast.

Best of luck.

Answer 9

cellular respiration and photosynthesis they both have electron transport chains in their INNER membranes they both have double membranes they are both organelles

Answer 10

they are organelles :p
