Question

In Amoeba, the process of digestion is ______________________.

• A. First in alkaline medium then in acidic medium
• B. First in acidic medium then in alkaline medium
• C. In alkaline medium only
• D. All of the above

Answer 1

The correct option is B First in acidic medium then in alkaline medium

• Digestion occurs in two process-acidic and alkaline.
• Amoeba has no digestive system.
• Food is digested inside the food vacuoles.
• Along with the body movements the food vacuoles are brought well inside the endoplasm.
• Inside the endoplasm, hydrochloric acid from the inner membrane of the vacuoles works on the food. It kills the living food materials and makes the contents acidic.
• Thus the acidic process is finished.
• Next alkali is secreted from the neighboring cytoplasm which brings the partly digested food material into the alkaline medium.
