Answer:
how does an amoeba obtain it's food ?
Amoeba envelops its food through the process of endocytosis or phagocytosis, where pseudopodia is created by flexibility of the plasma membrane.
The pseudopodia is the temporary arm-like projection in amoeba that helps collect the nutrition, alter its size and shape and acts as an organ of locomotion.
Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out. The complete phagocytosis process includes intake, digestion , absorption, assimilation, and egestion process.
what is osmosis ?
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.[Osmosis can be made to do work.Osmotic pressure is defined as the external pressure required to be applied so that there is no net movement of solvent across the membrane.
