Locomotion implies progression of an organism through the medium in which organism changes its place and position. A protozoan moves about in search of food material, protection and partners. Moreover, the progression is effected so as to adopt themselves to the new environment
Cycle in Man When an infected sand fly sucks the blood of man along with its saliva a number of promastigote forms enter the blood stream of man. Here they become amastigote forms by losing their flagella. It attacks the macrophage cell of liver or spleen. It appears to be well adapted to a life [...]
Leishmania is a haemoflagellate like Trypanosoma. It occurs as amastigote form in the vertebrate host and premastigote form in the invertebrate host. This protozoan is a digenetic as its life-cycle is passed in two hosts. The primary host is man and the secondary host is the sand fly (Phlebotomus sp). There are three very closely [...]
This free living protozoa reproduces by asexual and sexual methods. In Paremoecium, the asexual reproduction is caused by transverse binary fission. Binary Fission: Just before division the animal ceases feeding, the central portion of the body bulges. Micronucleus increases in size and fine spindle fibres are formed. Chromosomes divide eumitotically passing through all the stages [...]
Systematic Position of Paramoecium Sub-Kingdom- Protozoa Phylum- Ciliophora Genus- Paramoecium Species- caudatum Structure of Paramoecium Locomotion in Paramoecium As paramecium is a ciliate animal so it moves by its cilia. The rapid swimming is facilitated by the beating of fine and hair-like cellular organelles, called cilia, that cover the animal’s entire cell-body. Paramoecium moves with [...]
