Question

Write 2 similarities and dissimilarity between mitochondria and plastisides

Answer 1

1. A double membrane surrounding the organelles.

2.Both organelles have chemical cycles in which the initial acceptor is regenerated at the end of the cycle. In mitochondria, the Krebs cycle occurs after which oxaloacetate is regenerated at the end of the reaction. In chloroplasts, the Calvin cycle occurs in which ribulose bisphosphate is regenerated at the end of the reaction.

#dissimilarities-

1. Mitochondria are involved in cellular respiration whereas plastids (chloroplasts) are involved in photosynthesis. Thus, the overall chemical reactions for the processes occurring in them are different and reversed.

2. Mitochondria are found in all animal and plant cells. Chloroplasts, however, are found in only specific types of plant cells, such as the palisade mesophyll and spongy mesophyll cells of leaves
