Answer:
Analogous structures
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.
In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.
For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.

Protein synthesis in the ribosomes
The role of ATP synthase in photosynthesis is to transports a proton down the gradient and uses the energy to complete the phosphorylation of ADP to ATP.
Further Explanation:
Photosynthesis starts with the absorption of light or solar energy by the plant pigments called chlorophyll. The activated chlorophyll molecule helps in the electron transfer from one acceptor to another forming a chain.
The first phase of photosynthesis the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide. The first phase occurs in the grana region of the chloroplast and involves the transport of electrons through photosystem II (PS II) followed by photosystem I (PS I). The energy gained by the chlorophyll molecule is transferred to PS II in the form of electrons. These electrons are passed on further through a series of electron transporter or carrier from PS II to PS I. In photosystem I, finally, the electron is gained by NADP+ to form NADPH.
The ATP synthesis is produced by the use of proton motive force this reaction is catalyzed by ATP synthase. This a multiprotein synthase is also well-known as F0 F1 complex .The ATP molecule is synthesized when proton flow back from the inner membrane down the electrochemical proton gradient . ATP synthase has two components F1 ATPase and F0 which is embedded in the inner membrane and contain alpha, beta and C unit.
As the electrons travel along the electron transport chain, energy is released which helps in the pumping of protons (ions) into the lumen from the stroma through the thylakoid membrane. A proton gradient is developed which allows the movement of protons back to the stroma which in turn results in the formation of ATP through membrane-bound ATP synthase
The second phase of the photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.
