The eye is spherical in shape. The wall of the eye is composed of three layers or coats— an outer sclera, a middle choroid and an inner retina. The outermost layer or sclerotic coat is fibrous in texture. It preserves the form of the eyeball and protects the more delicate vascular and nervous coats within. [...]

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 [...]

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 [...]

Warner and Satir (1974) described the structure of a flagellum as seen under Electron Microscope. According to them various microtubules extending from the base to the tip of the flagellum construct the basic frame work of a flagellum. These are altogether eleven microtubules of which nine are situated at the periphery and two at the [...]
