Answer:
Dichloroindophenol chemical act as electron acceptor in photosynthesis
Explanation:
DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis
It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant  that is produced at the time of photosynthesis with in the chloroplasts.

Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.
