Can anyone help me with heterotrophic nutrition in paramecium using simple words?
Answers
FOR PARAMECIUM 1. Ingestion:
Paramecium engulfs food by the use of cilia. Cilia is a hair like structure present on surface on body of paramecium. Food is ingested by cilia through oral groove into gullet. The food is ingested with a little surrounding water to form a food vacuole
2. Digestion:
In Paramecium, food is digested in food vacuole by the digestive enzymes released by cytoplasm. Digestion in Paramecium is termed as “intracellular digestion”.
3. Absorption:
The digested food present in the food vacuole of Paramecium is absorbed directly into the cytoplasm by diffusion. After absorption of food, the food vacuole shrinks.
4. Assimilation:
The absorbed food nutrients is stored and utilised later for synthesis of energy.
5. Egestion:
The undigested food is expelled out through anal pore.
