Photosynthesis results in free electrons due to the energy from sunlight so there is also photon movement. In plants this happens in the chloroplasts. Chemiosmosis defines the movement of ions (hydrogen ions H+) which happens towards the thylakoid membrane from the stroma. I hope this answer helps.
Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
