Question

How does injection take place in paramoecium

Answer 1

Answer:

Paramoecium is unicellular animal which has a definite shape (slipper-like).

Paramoecium takes in food at a specific point (through oral groove to mouth to gullet). Food such as bacteria or very small organisms are move to the specific spot (ingestion point) by the movement of cilia which are present on all over the single-celled body.

From the gullet a food vacuole is formed which start circulating in the endoplasm. During circulation food is digested by enzymes. The digested food diffuses into the cytoplasm and undigested food is thrown out through anal pore.
