Growth of actin filaments to form bulges in the plasma membrane.

Explanation:

Actin filaments is a vital element in the body of unicellular organisms such as amoeba which is responsible for the movement of unicellular organism from one place to another. It also helps in the division of the cell and increase its population. This actin filament also helps the amoeba by engulf food substance for growth and survival.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
