What is the correct difference between excretion and egestion?
Answer and explanation
Correct answer: Excretion removes metabolic wastes and egestion removes undigested food
Excretion removes metabolic wastes produced by cellular activities, such as carbon dioxide, urea, and excess salts or water. Egestion is different: it is the elimination of undigested and unabsorbed food from the alimentary canal as faeces. Thus option A gives the correct distinction. Neither process produces oxygen, makes food, pumps blood, or opens stomata; those statements confuse unrelated functions.
