On the second page, I was not able to describe and explain the processes of diffusion, facilitated diffusion, osmosis, active transport,
endocytosis and exocytosis.
Endocytosis- involves engulfing of the material by the cell surface membrane to form a small sac. Exocytosi is the inverse of endocytosis.
