Describe locomotion of paranema

Answer 1

Peranema Patterson and Larsen, 1991

Paranema is a colorless phagotrophic euglenid, which does not readily swim, but glides along the grounds. It appears to have only a single, very broad emergent flagellum. (1) Paranema (also called Pseudoparanema) is a phagotroph and can manipulate other protists and detritus into the cell by means of two ingestion rods(3) The phase contrast photograph is supported with sketching to show more details in the cell ans will be provided on demand to dsdabhade@rediffmail.com.

The locomotion in this organism is gliding as it is in Amoeba proteous on the contrary it bears flagella which is also used during glinding movements. There are various stages of contraction and extension of the body.

1.During normal locomotion, the basal part remains fairly stiff, with only the anterior portion showing much activity. the flagella is thrown in the direction where the in which the animal has to move.

2. the vacuoles inside the protoplasm follow the way in which the flagella is thrown.

3. thus, the cell shows movements of the vacuoles as the bowl passes in the alimentary canal through peristalsis. You can imagine?

4. the complete cell body then is withdrawn and pulled towards the flagella.

The distance covered through this single movement is equals to the total length of the Paranema when extended.
