Compare the structure of mitochondria and chloroplast. What is common and difference?

Similarity:
● Two-membrane organoids. The outer membrane is flat, and the inner one forms numerous protrusions, which serve to increase the surface area. Between the membranes there is an intermembrane space.
● They have their own ring DNA molecules, all types of RNA and ribosomes.
● Capable of growth and reproduction by division.
● They synthesize ATP.

Differences:
● The protrusions of the inner mitochondrial membrane (crista) have the form of folds or ridges, and the protrusions of the inner membrane of chloroplasts form closed disc-shaped structures (thylakoids), collected in piles (grains).
● Mitochondria contain enzymes involved in cellular respiration. The inner chloroplast membrane contains photosynthetic pigments and enzymes involved in the conversion of light energy.
● The main function of mitochondria is the synthesis of ATP. The main function of chloroplasts is the implementation of photosynthesis.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
