* Food capture: Paramecia are single-celled organisms that use cilia, tiny hair-like structures, to create currents in the water. These currents bring food particles, such as bacteria and algae, towards the paramecium's oral groove.
* Ingestion: The oral groove leads to a mouth-like opening called the cytostome. The paramecium takes in food particles through the cytostome.
* Digestion: Once inside the paramecium, the food particles are contained within a food vacuole. This vacuole fuses with lysosomes, which contain digestive enzymes. These enzymes break down the food into smaller molecules that the paramecium can absorb.
* Absorption: The digested nutrients are absorbed from the food vacuole into the cytoplasm, the jelly-like substance that fills the paramecium.
* Waste removal: Undigested food waste is expelled from the cell through the anal pore.
Essentially, paramecia are like tiny little vacuum cleaners, sweeping up food particles and breaking them down for energy.
