Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The purpose of the oral groove in the paramecium is to
A
Pump out water
B
Move
C
Copy DNA
D
Capture food
Explanation: 

Detailed explanation-1: -The hair-like structures called cilia present on the paramecium help in collecting the food and movement. They sweep the food inside the paramecium through the oral groove. Waste is eliminated from the paramecium through the anal pore.

Detailed explanation-2: -The oral groove serves to guide food particles, primarily bacteria, into the pharynx (gullet). Food particles collect in the bottom of the cavity and are budded off into new food vacuoles.

Detailed explanation-3: -They eat other microorganisms like bacteria or algae by sweeping them towards their cell mouths (cytostomes) where they’re absorbed and digested. These cilia, however, are useful for more than just eating.

Detailed explanation-4: -It is a ciliated organism and has cilia on its cell surface to serve in locomotion. Cilia also serve to drive the food particles into the oral groove.

Detailed explanation-5: -The cilia, which stick out from the Paramecium’s outer coat of firm protein, known as the pellicle, don’t settle for just locomotion in their job descriptions. As they sway like vibrating feathers all along the edge of the organism, the cilia sweep food particles into the paramecium’s oral groove-a mouth of sorts.
