A pond, rich in various microorganisms, dries up due to drought. How will the amoeba in the pond protect themselves from this unfavorable condition?
By secreting a thick, protective sac around the cell membrane to prevent entry of water from the environment until favorable conditions emerge
By secreting a thick, protective wall around the cell membrane to prevent loss of water, forming a cyst until favorable conditions emerge
By secreting a thick cell wall which encloses many amoebae in it to prevent loss of water, forming a cyst until favorable conditions emerge
