A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. [2]
The final genome type found in plants and fungi is a linear genome made up of homogeneous DNA molecules (type 5). [22] [23] [24] Great variation in mtDNA gene content and size exists among fungi and plants, although there appears to be a core subset of genes present in all eukaryotes (except for the few that have no mitochondria at all).

Thermogenic plants are found in a variety of families, ... (AOX), which is an enzyme in the mitochondria organelle and is a part of the electron transport chain. [9]
Most are found in mitochondria, but some are found in peroxisomes of animals, in hydrogenosomes of anaerobic fungi, and in amyloplasts of plants. SLC25 is the largest solute transporter family in humans. 53 members have been identified in human genome, 58 in A. thaliana and 35 in S. cerevisiae .
The post-glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells. [citation needed] Although plants are net consumers of carbon dioxide and producers of oxygen via photosynthesis, plant respiration accounts for about half of the CO 2 generated annually by terrestrial ecosystems.

Plants and various groups of algae have plastids as well as mitochondria. Plastids, like mitochondria, have their own DNA and are developed from endosymbionts , in this case cyanobacteria . They usually take the form of chloroplasts which, like cyanobacteria, contain chlorophyll and produce organic compounds (such as glucose ) through ...
Mitochondria contain their own DNA. They are passed on by mothers to their children via the cytoplasm of the egg. Mitochondria are organelles which function to transform energy as a result of cellular respiration. Chloroplasts are organelles which function to produce sugars via photosynthesis in plants and algae.
Transport proteins called porins are found in the outer membranes of mitochondria and chloroplasts and are also found in bacterial cell membranes. [67] [68] [69] A membrane lipid cardiolipin is exclusively found in the inner mitochondrial membrane and bacterial cell membranes. [70]
