Answer:
The correct answer will be option-flagella; cilia.
Explanation:
The cellular movement and the movement of the environment surrounding the cell is accomplished by the hair-like projections which arise from the plasma membrane called the flagella and cilia.
The flagella are the long hair-like projections which help in the movement of the cells like sperm cells and the cilia are the short hair-like projections which help in the movement of the surrounding material of the cell.
Thus, the option-flagella; cilia is the correct answer.
