Question

Structure reproduction , life history of monocystis

Answer 1

Reproduction in Monocystis:

Monocystis reproduces sexually and the process of reproduction is complicated. Two mature trophozoites associate with each other for this purpose. They are called gametocytes or gamonts. They grow shorter and secrete round them a two-layered cyst called gametocyst.

Nutrition Required by Monocystis:

The adult trophozoite is suspended in the nutrient fluid meant for the nourishment of the earthworm’s spermatozoa. It is sur­rounded by soluble food which is absorbed into the endoplasm by slow diffusion through its porous cuticle. The young trophozoite lives within the sperm mother cell of the earthworm.

It secretes digestive enzymes from its outer surface which dissolve the proto­plasm of the sperm mother cell. The digested product is then absorbed by diffusion through the cuticle. The parasite requires no food vacuole, because it either gets digested food or digests food outside its own body. As the parasite absorbs soluble food through the outer surface of its body, the mode of nutrition is saprozoic.
