Question

‘Slipper animalcule’ is
A. Entamoeba
B. Paramecium
C. Giardia
D. Euglena

Answer 1

Hint: The term slipper is used for defining the shape of the organism. The word animalcule denotes microscopic organisms. Thus, representing the animals that are very small in size. The word Animalcule was given by Antonie van Leeuwenhoek to refer to the microorganisms that he observed in rainwater.

Complete answer:
Paramecium is a unicellular creature with a shape looking like the sole of a shoe. It ranges from 50 to 300um in size which fluctuates from species to species. It is generally found in a freshwater environment. It is a solitary celled eukaryote having a place with the Protista and is a notable class of ciliate protozoa. Slipper animalcule is a typical name for the ciliated protozoan Paramecium. The term slipper is utilized because their shape resembles a slipper and the animalcule term speaks to the minute life form. Consequently, the right answer is 'Paramecium'.

Hence, option B is correct
Additional Information: Paramecium caudatum is 170–330 micrometers in length (generally 200–300 micrometers). The phone body is shaft molded, adjusted at the front, tightening at the back to an unpolished point. Early microscopists compared its shape to that of a slipper, and normally alluded to it as the "slipper animalcule." The pellicle is consistently secured with cilia, and has a long oral furrow, prompting profoundly implanted oral pits, fixed with cilia (short, hair-like protoplasmic measures that fill in as organs of motion and food catch).

Note: Paramecium is a unicellular having the sole of a shoe shape. It ranges from 50 to 300um in size which fluctuates from species to species. The slipper and the animalcule term speaks to the minute life in its shape form.
