Question

how does excretion takes place in unicellular organisms​

Answer 1

Its metabolic wastes such as CO2and ammonia simply diffuse through the plasma membrane into the surrounding water. Particulate debris remaining from undigested food is removed by the exocytosis of a waste vacuole merging with the surface membrane.

Answer 2

Answer:

Due to the lack of specialised organs for the elimination of waste products in unicellular organisms, wastes are eliminated directly through the cell membrane via diffusion.

Explanation:

• Excretion is the process of an organism's waste being removed from its body as a result of metabolic activity and energy production. It is a necessary procedure for all living things.
• Unicellular creatures, such as Amoeba, are made up of a single cell. As a result, in unicellular organisms, a single cell performs all functions. Unicellular creatures eliminate waste from their bodies by diffusing it into the surrounding water.
