Chloroplasts are the plastids that contain a green pigment called chlorophyll. Chlorophyll produces energy through photosynthesis and other oxygen-releasing processes. They also take part in the biosynthesis of amino acids, vitamins, lipids etc.

“Osmosis is the term used to refer specifically the diffusion of water across a differentially or selectively permeable membrane.” Yes, osmosis is a special type of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region.

Sanaj Dahiya 4 months, 4 weeks ago

Osmosis is diffusion through semipermeable membrane. Diffusion can take place in all 3 states (solid, liquid, gas) but osmosis take place only in liquid. And in diffusion, the movement of either solute or solvent occurs in both directions whereas in osmosis there is only undirectional flow of solvent. Hence, osmosis is a special kind of diffusion.
