What is the process of ingestion of food in amoeba and paramecium
Answers
Explanation:
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.11
FOR AMOEBA
Amoeba is a unicellular protozoan and the mode of nutrition is holozoic. It is omnivorous in nature i.e, it can take both plants and animals as food source. Amoeba feeds on unicellular plants or animals such as paramoecium. The various steps of nutrition are ingestion, digestion, assimilation and egestion.
Amoeba sends out finger like pseudopodia up on contact with food and engulfs the food by the process called ingestion. This results in the formation of food vacuole.
Food vacuole releases digestive juices, that results in the breakdown of complex food particles into simple molecules by the process digestion.
The digested food diffuses into the cytoplasm by the process called assimilation. The undigested food is thrown out of the body by the food vacuole, this process is called as egestion
Answer:
Ingestion is the taking in of food .
