Question

what type of asexual reproduction method does occur in a planaria other than regenration

Answer 1

A drop of pond water might look clear and lifeless. But look again. There's something visible to the naked eye, like small black worms, writhing and slithering. Zoom in closer, and two beady -- but almost cute -- eye spots peer up at you.

The eye spots detect light.

These are ,planarian worms a type of flatworm in the Phylum Platyhelminthes and the Class Turbellaria. They are very common classroom organisms, with a simple body plan. The species in the photo here is Dugesia subtentaculata.

These worms are, famously, immortal when cut lengthwise or in half -- something that seems straight out of a science fiction movie. If you cut one of these little flatworms, the two halves will grow into two new, whole organisms with the same genetic pattern. Pluripotent stem cellsallow the planarians to regrow and replicate. These stem cells have the ability to generate any planarian tissue, a process, known as regeneration. Regeneration has far-reaching effects on aging and medical research. In this lesson, we'll discuss planarian reproduction, which includes both sexual reproduction and the fascinating asexual process of regeneration.

The image here highlights the simple reproductive anatomy of planarian worms. Planaria are hermaphriditic, meaning they have both male and female sex organs.

An overview of the planarian reproductive system anatomy.

The ovaries are located in a rostral direction, near the eyespots. This is, of course, very different from the location of the ovaries in the lower abdominal body cavity of humans! Planarian ovaries create a single egg cell.

Testes are located laterally, along the sides of the body, along with seminal ducts, which together create and transport sperm. Planarian worms also have a penis, which is housed in a genital chamber. Eggs are supplied with nutrients via specialized yolk glands.

Answer 2

may be there is no other method
