from the external environment options exosmosis endosmosis p l a s m o l y s i s all of them

Answer 1

The appropriate answer here would be endosmosis.
Endosmosis is the process by which materials would move to the selectively into the amoebas through the selectively permeable amoeba's cell wall. 

Exosmosis is the process by which the materials move out the amoeba by the process of osmosis(opposite of endosmosis).

Plasmolysis is the process by which the plant cell wall collapses due to loss of water by a plant cell to the environment.
