Explain the structure and life cycle of entamoeba hydrolytic?
Answers
Entamoeba histolytica passes three distinct stages in its life cycle they are
✍️Trophozoite stage
✍️Pre cystic stage
✍️ Cystic stage
Trophozoite stage:
It is the most active motile feeding in pathogenic states that lives in the mucosa and submucosa membranes of large intestine it has following parts in the body .The body of the proposed it surrounded by plasmalemma It's ectoplasm is differentiated into outer clear discourse non granular cytoplasm and inner fluid like granular endoplasm .Ribosomes Football skills and vesicular V shaped nucleus are present in endoplasm contractile vacuole ribosomes endoplasmic reticulum Golgi apparatus and mitochondria are absent .It's anterior end has single finger like blunt pseudo podium called lobopodium .Presence of RBC in food vacuoles and c hand cartwheel shaped nucleus are the characteristic features of proposals of entamoeba histolytica .It producers proteolytic enzyme called distalizer medicines view questions of glucose of cut war and releases blood tissue debris suggested by the trophozoite.
Pre-cystic stage:
It is in then on feeding and lie non-pathogenic stage of entamoeba histolytica that is found in the lumen of the large intestine .It is is small spherical or oval non motile form .The cytoplasm of precystic state stores glycogen granules and chromatic bus made of ribonucleoprotein which act as a reserve food .
Cystic stage
It is founding lumen of the large intestine and round in shape and surrounded by a team delicate and highly resistant cyst wall.The process of development of festival is called encystation which is a means to tide over the unfavourable conditions while passing to new host so after encystation the nucleus undergoes two successive mitotic divisions to form for daughter nuclei is type of cystic state is called tetranucleate system system which is infective stage to man.
