EVERYDAY SCIENCE

Detailed explanation-1: -Paramecia are completely covered with cilia (fine hairlike filaments) that beat rhythmically to propel them and to direct bacteria and other food particles into their mouths. On the ventral surface an oral groove runs diagonally posterior to the mouth and gullet.

Detailed explanation-2: -Paramecium are heterotrophs, meaning they must consume food for their energy. The area of the paramecium that appears pinched inward is called the oral groove, which runs about half the length of its body. Cilia sweep food into this area and into the gullet, where food vacuoles are formed.

Detailed explanation-3: -Oral groove: Appearing as a depression on one side of the body. The oral groove extends from the anterior end to beyond the middle. 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-4: -Paramecium are heterotrophs, meaning they must consume food for their energy. Food enters the paramecium through the mouth pore (color orange) and goes to the gullet (color dark blue). At the end of the gullet, food vacuoles are formed. Food vacuoles then remain in the cytoplasm until the food is digested.

Detailed explanation-5: -What does the gullet do in a paramecium? Gullet in a paramecium acts as buccal cavity where the food is converted into food vacuoles for digestion.
