HSEB notes |Paramacium caudatum is halozoic in nutrition. It's food consists of minute living organisms like bacteria, unicellular algae, diatoms, yeasts etc. Ingestion of food takes place with the help of specialized cilia which filters food.
The food material passes into the cytopharynx through cytomsome and finally settle down into the reservoir. Digestion takes place with the help of certain enzyme secreted by protoplasm into the vacuole. During digestion, protein is changed into amino acid, carbonhydrate is changed into soluble sugar and glycogen and fats are also probably digested.
The content of food are at first acidic ( ph about 4 ) and then become alkaline. The major digestion of food occurs during alkaline phase. A food vacuole is formed at the end of cytopharynx and when the food vacuole becomes full it leaves into endoplasm independently.
Digested food gets distributed in the endoplasm by cyclosis and undigested food material are excreted out through cytophyge
