Plzzz ! the protist seen here is called euglena. it is both animal-like and plant-like. it eats food but it also has chloroplasts like a plant cell, in order to make food. the euglena has one structure that it move. it is visible here. what is that cellular structure? a) cilia b) flagellum c) ribosomes d) golgi bodies

Option B, flagellum

Explanation:

Flagellum is a locomotory organ in Euglena that allows it to move through the water. A flagellum is located on the front or anterior side of body of euglena. It looks like a thread like structure which is capable to act like a motor.

Euglena can whip it flagella just like a helicopter propeller and thus it comes under the species category of "species with falgellatory locomotion"

Hence, option B is correct

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
